-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: sudo Announcement-ID: SuSE-SA:2002:014 Date: Tue Apr 30 16:00:00 MEST 2002 Affected products: 6.4, 7.0, 7.1, 7.2, 7.3, 8.0, SuSE Firewall Adminhost VPN, SuSE Linux Admin-CD for Firewall, SuSE Linux Enterprise Server, SuSE Linux Connectivity Server Vulnerability Type: local privilege escalation Severity (1-10): 6 SuSE default package: yes Other affected systems: All systems with sudo installed. Content of this advisory: 1) security vulnerability resolved: Heap overflow in sudo. problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The sudo program allows local users to execute certain configured commands with root priviledges. Sudo contains a heap overflow in its prompt assembling function. The input used to create the password prompt is user controlled and not properly length-checked before copied to certain heap locations. This allows local attackers to overflow the heap of sudo, thus executing arbitrary commands as root. We would like to thank GlobalInterSec for finding and researching this vulnerability. As a temporary workaround you may remove the setuid bit from sudo by issuing the following command as root: "chmod -s /usr/bin/sudo". Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. i386 Intel Platform: SuSE-8.0 ftp://ftp.suse.com/pub/suse/i386/update/8.0/ap1/sudo-1.6.5p2-79.i386.rpm b54f68ff4b32f9d920f2f1ff887d1ddc source rpm: ftp://ftp.suse.com/pub/suse/i386/update/8.0/zq1/sudo-1.6.5p2-79.src.rpm fd1ccf6fe52c6b999c5ed24a2f3a4e65 SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/ap1/sudo-1.6.3p7-83.i386.rpm 80edbf5caf02c519cf2c01d6ba76d22f source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/sudo-1.6.3p7-83.src.rpm 77962932840740ce5e3dfe57a887592d SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/ap1/sudo-1.6.3p6-92.i386.rpm 669aa8db134e39f462cb9f2648f6735f source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/sudo-1.6.3p6-92.src.rpm 249b1ef0135dcfede3648982900e277c SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/ap1/sudo-1.6.3p6-91.i386.rpm 6b3b84f0a4c687e91da179937b87048a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/sudo-1.6.3p6-91.src.rpm bf59a6b200a0fb130f3528ce23698be0 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/ap1/sudo-1.6.3p6-90.i386.rpm 5b67ef9fed383242111953d942c62174 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/sudo-1.6.3p6-90.src.rpm c35f6390b360500b7b649e4590a748cc SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/ap1/sudo-1.5.9p1-87.i386.rpm 82d98116eccc73c7a0ce03a51e9b5378 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/sudo-1.5.9p1-87.src.rpm e75e2608036a963a7339fe4632a2550b Sparc Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/ap1/sudo-1.6.3p7-33.sparc.rpm bd492b6d601ceb30486e3e970a2211a3 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.3/zq1/sudo-1.6.3p7-33.src.rpm d2435d180cdd76647e1f1416e93c2420 SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/ap1/sudo-1.6.3p6-37.sparc.rpm bbad36265f93fac25d59f8c26b1ccd52 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/sudo-1.6.3p6-37.src.rpm a328d2eb0fdc816341a68febfeb5a33a SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/ap1/sudo-1.6.3p6-36.sparc.rpm 48e7b360b45bae0b3e9e90b3bf945f75 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/sudo-1.6.3p6-36.src.rpm bd8f11a8916340e0d243ae1cc647df26 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/ap1/sudo-1.6.3p6-40.alpha.rpm 4505dd58fe309ef0a4515db6a6980ec4 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/sudo-1.6.3p6-40.src.rpm 85dfbe40da4d93d54d3c16f6489a7f32 SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/ap1/sudo-1.6.3p6-40.alpha.rpm b67858459774e5e04c9c22e84d5899ff source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/sudo-1.6.3p6-40.src.rpm 6d0537068d16785bfdbca936c6395abb PPC Power PC Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/ap1/sudo-1.6.3p7-65.ppc.rpm 1734f578b1fa87c26e51a11e3dc90d18 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/sudo-1.6.3p7-65.src.rpm ebff8b3e7b86ef9bb69fb13da37903ce SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/ap1/sudo-1.6.3p6-45.ppc.rpm 4318adbde184c1c8fff6eb581f02c11e source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/sudo-1.6.3p6-45.src.rpm 771f9e7f6d1fc1ba4df119147e48ddcd SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/ap1/sudo-1.6.3p6-45.ppc.rpm 6ae150cfa793f20e49ed751aa686fdea source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/sudo-1.6.3p6-45.src.rpm ede5fedf45ffe6b59c43e082fcef50f4 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/ap1/sudo-1.5.9p1-85.ppc.rpm 0677a205615f631a41ca308be03db7bd source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/sudo-1.5.9p1-85.src.rpm 71da4a7d43043b20eefd5e05048616d8 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - ifup-dhcp could be tricked into executing arbitrary commands as root by DHCP servers handing out illegal values (e.g. containing spaces), because it sourced dhcpcd's info file, where not all variable values are quoted. This problem has been fixed. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: radiusd-cistron Announcement-ID: SuSE-SA:2002:013 Date: Mon Apr 29 13:00:00 CEST 2002 Affected products: 6.4, 7.0, 7.1, 7.2, 7.3, Enterprise Server 7 Vulnerability Type: remote command execution Severity (1-10): 7 SuSE default package: No Other affected systems: Various radius clients and servers. Content of this advisory: 1) security vulnerability resolved: digest calculation buffer overflow, invalid attribute length calculation problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The radius daemon as shipped with the radiusd-cistron package is responsible for the RADIUS authentication service in networks and therefore considered a security critical application. ZARAZA reported security releated bugs in various radius server and client software. The list of vulnerable servers includes the cistron radius package. Within the cistron package, a buffer overflow in the digest calculation function and miscalculations of attribute lengths have been fixed which could allow remote attackers to execute arbitrary commands on the system running the radius server. Beside the cistron radius package the following radius packages have been vulnerable to the same attacks and have been fixed: freeradius, radiusclient and livingston-radius. The only workaround for this bug is to disable the radius-server until the new packages have been installed. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. Once you successfully updated your radius packages, make sure you restart the radius server by issuing the following command as root: "/etc/rc.d/radiusd restart" "/etc/rc.d/radiusd" automatically invokes the correct radius-server which is part of either the cistron, livingston or freeradius package. i386 Intel Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n3/radiusd-cistron-1.6.4-168.i3… 8215e7113e8937844ab5d2deba8bbb13 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/radiusd-cistron-1.6.4-168.s… 978edf49cf7fa28c5e872bc48ba504ab SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n3/radiusd-cistron-1.6.4-167.i3… 964904ef67f81b2d19f1c8ef2ccc6f61 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/radiusd-cistron-1.6.4-167.s… 6ffd720c4ceb0e0c6d22446178d8bf11 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n3/radiusd-cistron-1.6.4-168.i3… 52ec1da0c4b750fe63d506713ff56c5e source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/radiusd-cistron-1.6.4-168.s… 6d34cc16bf9adcc93eac095570f49748 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n2/cistron-1.6.3-76.i386.rpm 52a9b0c7fcbd45973db6508d155edf21 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/cistron-1.6.3-76.src.rpm a22a646d5f04dd853906db9cc465f14a SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n2/cistron-1.6.2-25.i386.rpm bed8804bf53822d7f7bcdd54f00a9d89 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/cistron-1.6.2-25.src.rpm b47877d68465e895fe899da9ba89709d Sparc Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n3/radiusd-cistron-1.6.4-65.sp… 3230120f925437fd36b648991a3b4851 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.3/zq1/radiusd-cistron-1.6.4-65.s… 713f6f1f7fe4c2987a52b12df6ef2c4a SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n3/radiusd-cistron-1.6.4-65.sp… d444432bd863523992620401311f948b source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/radiusd-cistron-1.6.4-65.s… ff7a7f432a0a32fbed31a6ee680d5118 SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/n2/cistron-1.6.3-4.sparc.rpm 69ee7178a0312685a169386180cd5e9e source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/cistron-1.6.3-4.src.rpm 71632b60b9b2bee4df06f940088b0ab6 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n3/radiusd-cistron-1.6.4-69.alph… 323032020d8c82724b12904db456c135 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/radiusd-cistron-1.6.4-69.src… 7440831ddb1e394ac6595e9e5bebbff1 SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/n2/cistron-1.6.3-8.alpha.rpm 4deb36542c3a76a9246618abcd656d96 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/cistron-1.6.3-8.src.rpm 77c3cfe8cb64d7c2cd59b81e0e1e26ea SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/n2/cistron-1.6.2-20.alpha.rpm 0c39bec71f6671c55b46ed627f2830d9 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/cistron-1.6.2-20.src.rpm 8783c9b8f519a1623bf6df52a8878ab0 PPC Power PC Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n3/radiusd-cistron-1.6.4-95.ppc.… a541869da6cfa45822887dc69f7730f8 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/radiusd-cistron-1.6.4-95.src… da491549cda05ead01d2dd0519f14eeb SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n3/radiusd-cistron-1.6.4-95.ppc.… 998f87b937ec36e55ee0151f82a071fa source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/radiusd-cistron-1.6.4-95.src… ebb96d0b9b5093a5324c90743f7a69a3 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n2/cistron-1.6.3-85.ppc.rpm 7258462a504e594f07433f342b0870c1 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/cistron-1.6.3-85.src.rpm d6ebb9cdd5c3538eae2db805f6fda97b SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/n2/cistron-1.6.2-21.ppc.rpm 6274908e60a8ff24a3be7c4936b36d90 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/cistron-1.6.2-21.src.rpm aa350c9fedc384c382744b4b2563250c ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - mtr A buffer overflow was found in mtr, which enables an attacker to get access to mtr's raw socket. Fixed RPM packages are available from our ftp servers. Additionally you should remove the setuid bit from mtr and add an appropriate entry in /etc/permissions.local. - webalizer A possible buffer overflow in the webalizer DNS resolv code was found. The bug seems no to be exploitable. The SuSE Security Team fixed this and other possible bugs in the webalizer code. New RPM packages will be available on our FTP servers. - ntop Version < 2.0.99 of ntop could be crashed by feeding ntop's HTTP code with invalid URL's. This bug does not exist in ntop version 2.0.1 which is shipped with SuSE 8.0. - slrnpull Problems with slrnpull have been reported on the bugtraq mailinglist. SuSE does not ship this program setuid and is therefore not vulnerable to the buffer overflow attack against this program. - openssh Niels Provos published a local exploitable bug for OpenSSH. This bug could only be exploited if Kerberos and AFS support was enabled while compiling OpenSSH. The OpenSSH RPM file that comes with SuSE hasn't enabled Kerberos nor AFS, so we are not vulnerable to this attack. The bug will be fixed with the next security update of OpenSSH. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: ucdsnmp Announcement-ID: SuSE-SA:2002:012 Date: Monday, Apr 8th 2002 11:37 MEST Affected SuSE versions: 6.4, 7.0, 7.1, 7.2, 7.3 SuSE Linux Database Server SuSE eMail Server III SuSE Firewall SuSE Linux Connectivity Server SuSE Linux Enterprise Server 7 Vulnerability Type: - remote root access - remote denial-of-service Severity (1-10): 6 SuSE default package: no Other affected systems: all linux-like systems using ucdsnmp Content of this advisory: 1) security vulnerability resolved: serveral bugs in ucdsnmp problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The Secure Programming Group of the Oulu University, Sweden released a testing suite for SNMP implementations. Several bugs could be triggered in the ucd-snmpd code by using this testing suite. These bugs lead to remote denial-of-service attacks and may possibly exploited to break system security remotely. Additionally, the SuSE Security Team did a full audit of the ucd-snmpd code and we hope to avoid more problems caused by other bugs in the future. Generally SNMP access (UDP 161,162) and all UDP bouncing services like echo (UDP 7) should completely be blocked at your firewall. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. After updateing the RPM package run "ldconfig" and "rcsnmpd restart" as root to make the new library effective and to start the new daemon. Please note! We made a version upgrade of ucdsnmp, so other programs that rely on the ucdsnmpd library may become broken. We are aware of the following dependencies: - ethereal - gxsnmp - mod_php4 - snmp - tngfw New RPM packages for this programs will be released as soon as possible. The mod_php4 packages have been published and require the new ucdsnmp packages. i386 Intel Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n2/ucdsnmp-4.2.3-79.i386.rpm 1c2e1cb902a7bfd1235b72ab01ef8fb5 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.3/zq1/ucdsnmp-4.2.3-79.src.rpm 4690d8fdd02aeda1ecdfb823ee4e5c5b SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/n2/ucdsnmp-4.2.3-79.i386.rpm 8d64235fb11291264a77df5dbcccc92d source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/ucdsnmp-4.2.3-79.src.rpm 64ea35f0f89fda979050e0276a9a1454 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n2/ucdsnmp-4.2.3-79.i386.rpm 89d6afe19dde9d69269ba59941db9ed8 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/ucdsnmp-4.2.3-79.src.rpm 226cd20a4f287c3ed518443070ba5a1b SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/ucdsnmp-4.2.3-79.i386.rpm d83d0eacc2ee9aeb9d48106c5ccc5d86 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/ucdsnmp-4.2.3-79.src.rpm 7b39de0fa0632f845da6bc0868ae7a50 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/n1/ucdsnmp-4.2.3-79.i386.rpm 0f07af8b74bff747d0a08158ebce13e0 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/ucdsnmp-4.2.3-79.src.rpm adc89756a09334dcb4a392079b40bc63 Sparc Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/sparc/update/7.3/n2/ucdsnmp-4.2.3-30.sparc.rpm 2bf9c52997928890eb39e74ebd279a96 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.3/zq1/ucdsnmp-4.2.3-30.src.rpm ae8896d82ba79d65b7a9efdc681d61e2 SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n2/ucdsnmp-4.2.3-30.sparc.rpm 29b37eecda93c9c40eeafc7c6f2150b5 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/ucdsnmp-4.2.3-30.src.rpm 6510ed2805dc225dfe0f2576e082d518 SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/n1/ucdsnmp-4.2.3-30.sparc.rpm 97ff495d2e5a25fbd403ac60d953fb67 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/ucdsnmp-4.2.3-30.src.rpm 2bf034b9ccfc8e18915c9ad043c3f031 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/n2/ucdsnmp-4.2.3-39.alpha.rpm 1d1b6039a7ff00146395d9b47f79cd8a source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/ucdsnmp-4.2.3-39.src.rpm b9e13edaae7adc6325088d562687ae12 SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/n1/ucdsnmp-4.2.3-39.alpha.rpm 1f3e6df23a387747f025916e42d56e4d source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/ucdsnmp-4.2.3-39.src.rpm d8b0005133f9a1129d1b5cd821999d20 SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/n1/ucdsnmp-4.2.3-39.alpha.rpm ee584501afdf1e3246d48ef0648e40f9 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/ucdsnmp-4.2.3-39.src.rpm 1ffda4dc5f0cd611de0c45305849b314 PPC PowerPC Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/ppc/update/7.3/n2/ucdsnmp-4.2.3-63.ppc.rpm 43d3afe225546fac26d64b78439c2659 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.3/zq1/ucdsnmp-4.2.3-63.src.rpm 7859b62cc34b7bd6638beca85e6c72d6 SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n2/ucdsnmp-4.2.3-63.ppc.rpm 583bf560618c865daafb7219f230666d source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/ucdsnmp-4.2.3-63.src.rpm 528a0127706acd1586846d8c85dcee49 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n1/ucdsnmp-4.2.3-63.ppc.rpm 8bcb36e2ad94472564ee94449590a362 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/ucdsnmp-4.2.3-63.src.rpm e3f20e08881a22f73376cacf4f9a5606 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/n1/ucdsnmp-4.2.3-63.ppc.rpm 4a9e00c6e07230f156b4382e97028b29 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/ucdsnmp-4.2.3-63.src.rpm 5464ea7488c5fd9e8f0617833a296fbf ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - inn update packages are available for the inn news server, as contained in all SuSE Linux products. The updates fix a problem where the inews program wouldn't properly check the moderator's email address that is supplied by the server. The user calling inews may gain elevated local privileges with this bug. In addition to the fix for this particular bug, minor directory permission adaptions have been made. We will not release an own security announcement for this bug. - gnokii for SuSE-7.2 and SuSE-7.3 The gnokii package for the SuSE Linux distributions contain a vulnerability that allows write access to any file on the system, allowing a local attacker to gain root privileges. Update packages for the SuSE Linux Distributions 7.2 and 7.3 are avbailable on our ftp server that fix this problem. We will not release an own security announcement for this bug. - mod_php4 for SuSE Linux 7.2 A packaging error caused the update packages for the mod_php4 package on SuSE Linux 7.2 to lack support for TTF, XML and IMAP. This has been corrected with new update packages on the ftp server. - fileutils A race condition while recursively removing directory structures from world-writeable directories cause the rm(1) command to be vulnerable to an attack that allows a local user to remove arbitrary directories (and files) from the system. The error has been corrected in the update packages that are available from the a1/ series update directrory of each distribution. Users of SuSE Linux Enterprise Server 7 based products receive their update packages through the SuSE maintenance web. We will not release an own security announcement for this bug. - nscd The name service cache daemon shipped with supported SuSE products (part of the glibc/shlibs package) is configured to run by default, but configured to not cache hosts entries (A- and PTR records from domain name servers). Therefore, a vulnerability that takes advantage of the fact that nscd uses an existing (cached) PTR record for resolving a request for an A-record is not applicable to SuSE products. The weakness will be fixed in future releases of SuSE products. ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion. All SuSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SuSE's announce-only mailing list.
