Chaps and chapesses, does anyone out there know a good location or doc for firewall security with Oracle? Metalink (Oracle's site doesn't seem to be too hot). Inside / Outside the firewall pro's and con's issues, how to set up that sort of thing. On Linux of course. Is there a firewall version of Linux? Is it not just normal Linux with some packages installed and some tweaking? Am I barfing up the wrong tree? This message is confidential and may also contain privileged information.

SuSE Security Announcement: radiusd-cistron (SuSE-SA:2002:013)
by Sebastian Krahmer 29 Apr '02

29 Apr '02

-----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.

User Password Change does not Propagate to IMP Server
by Wilmer Geovanny 28 Apr '02

28 Apr '02

When a User changes his Password by means of his shell prompt, with the passwd command, the user cannot access anymore to his mail box by means of the IMAP server. This is the only server that does not get known of the change. Well, SuSE Linux 7.3 and when the password is changed by the Yast utility, everything works great. It seems that there is some script missing to be running.

User: nobody ?
by Simon Dorfman 28 Apr '02

28 Apr '02

Hello, I found the user: "nobody" running "find" on my machine. My first thought was that someone had hacked in. My second thought was that maybe suse runs some commands on it's own as "nobody." Does anyone know if the latter is true? Thanks, Simon(a)SimonDorfman.com http://SimonDorfman.com

Firewall Rule 14
by alessandro.de.bertoldi 26 Apr '02

26 Apr '02

hi, i would like to access the dbase-server (192.168.1.5) from home (xxx.xxx.xxx.104). i changed the firewall2-rule, so the firewall is now forwarding my request with this ip to the db-machine. the result is, that the firewall has now forwarding ALL web requests (192.168.1.6) to the db machine Rule 14. FW_FORWARD_MASQ="xxx.xxx.xxx.104,192.168.1.5,tcp,80 0/0,192.168.1.6,tcp,80" what is wrong with this rule ? i try also FW_FORWARD_MASQ="xxx.xxx.xxx.104/0,192.168.1.5,tcp,80 0/0,192.168.1.6,tcp,80" thank you
