-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: bind8 Announcement-ID: SuSE-SA:2003:047 Date: Friday, Nov 28th 2003 15:30 MEST Affected products: 7.3, 8.0, 8.1, 8.2 Vulnerability Type: cache poisoning/denial-of-service Severity (1-10): 5 SUSE default package: yes Cross References: CAN-2003-0914 Content of this advisory: 1) security vulnerability resolved: - caching negative answers problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - ethereal - KDE - mc - apache1/2 - gpg - freeradius - xscreensaver - screen - mod_gzip - gnpan 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information To resolve IP addresses to host and domain names and vice versa the DNS service needs to be consulted. The most popular DNS software is the BIND8 and BIND9 suite. The BIND8 code is vulnerable to a remote denial-of-service attack by poisoning the cache with authoritative negative responses that should not be accepted otherwise. To execute this attack a name-server needs to be under malicious control and the victim's bind8 has to query this name-server. The attacker can set a high TTL value to keep his negative record as long as possible in the cache of the victim. For this time the clients of the attacked site that rely on the bind8 service will not be able to reach the domain specified in the negative record. These records should disappear after the time-interval (TTL) elapsed. There is no temporary workaround for this bug. To make this update effective run "rcnamed restart" as root please. 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.

An update package is currently being tested and will be released as soon as possible. - KDE New KDE packages are currently being tested. These packages fixes several vulnerabilities: + remote root compromise (CAN-2003-0690) + weak cookies (CAN-2003-0692) + SSL man-in-the-middle attack + information leak through HTML-referrer (CAN-2003-0459) + wrong file permissions of config files The packages will be release as soon as testing is finished. - mc By using a special combination of links in archive-files it is possible to execute arbitrary commands while mc tries to open it in its VFS. The packages are currently tested and will be release as soon as possible. - apache1/2 The widely used HTTP server apache has several security vulnerabilities: - locally exploitable buffer overflow in the regular expression code. The attacker must be able to modify .htaccess or httpd.conf. (affects: mod_alias and mod_rewrite) - under some circumstances mod_cgid will output its data to the wrong client (affects: apache2) The new packages are available on our FTP servers. - gpg In GnuPG version 1.0.2 a new code for ElGamal was introduced. This code leads to an attack on users who use ElGamal keys for signing. It is possible to reconstruct the private ElGamal key by analyzing a public ElGamal signature. Please note that the ElGamal algorithm is seldomly used and GnuPG displays several warnings when generating ElGamal signature keys. The default key generation process in GnuPG will create a DSA signature key and an ElGamal subkey for _encryption only_. These keys are not affected by this vulnerability. Anyone using ElGamal signature keys (type 20, check fourth field of "gpg --list-keys --with-colon" output) should revoke them. - freeradius Two vulnerabilities were found in the FreeRADIUS package. The remote denial-of-service attack bug was fixed and new packages will be released as soon as testing was successfully finished. The other bug is a remote buffer overflow in the module rlm_smb. We do not ship this module and will fix it for future releases. - xscreensaver The well known screen-saver for X is vulnerable to several local tmp file attacks as well as a crash when verifying a password. Only SuSE Linux 9.0 products are affected. The new packages are available on our FTP servers. - screen A buffer overflow in screen was reported. Since SuSE Linux 8.0 we do not ship screen with the s-bit anymore. An update package will be released for 7.3 as soon as possible. - mod_gzip The apache module mod_gzip is vulnerable to remote code execution while running in debug-mode. We do not ship this module in debug-mode but future versions will include the fix. - gnpan A remote denial-of-service attack can be run against the GNOME news-reader program gnpan. This bug affects SuSE Linux 8.0, 8.1, 8.2. Update packages are available on our FTP servers. ______________________________________________________________________________ 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 un-installed 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 top-level 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.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: sane Announcement-ID: SuSE-SA:2003:046 Date: Tuesday, Nov 18th 2003 14:30 MEST Affected products: 7.3, 8.0, 8.1 SuSE Linux Desktop 1.0 Vulnerability Type: remote denial-of-service Severity (1-10): 5 SUSE default package: yes Cross References: CAN-2003-0773 CAN-2003-0774 CAN-2003-0775 CAN-2003-0776 CAN-2003-0777 CAN-2003-0778 Content of this advisory: 1) security vulnerability resolved: several security vulnerabilities problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - ethereal - KDE - KDE wrong file permissions - ircd - mc - apache1/2 - proftpd - gdm2 - epic/epic4 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The sane (Scanner Access Now Easy) package provides access to scanners either locally or remotely over the network. Several bugs in sane were fixed to avoid remote denial-of-service attacks. These attacks can even be executed if the remote attacker is not allowed to access the sane server by not listing the attackers IP in the file sane.conf. Per default saned only accepts local requests. As a temporary workaround saned can be started via xinetd or inetd in conjunction with tcpwrapper to restrict remote access. 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.

These packages fixes several vulnerabilities: + remote root compromise (CAN-2003-0690) + weak cookies (CAN-2003-0692) + SSL man-in-the-middle attack + information leak through HTML-referrer (CAN-2003-0459) The packages will be release as soon as testing is finished. - KDE wrong file permissions Due to a missing synchronisation during SuSE Linux 8.2 beta-testing phase some configuration files of KDE on SuSE Linux 8.2 are world- writeable. Please check the files in /etc/opt/kde3/share/config and add an appropritae line to /etc/permissions.local, like: /etc/opt/kde3/share/config/kmailrc root.root 0644 /etc/opt/kde3/share/config/kioslaverc root.root 0644 /etc/opt/kde3/share/config/kdeglobals root.root 0644 Set the new permission with 'chkstat -set /etc/permissions.local' as root. - ircd The Internet Relay Chat daemon is vulnerable to a remote denial-of- service attack. The attack can be triggered by irc clients directly connected to the daemon. Update packages are available on our FTP servers. - mc By using a special combination of links in archive-files it is possible to execute arbitrary commands while mc tries to open it in its VFS. The packages are currently tested and will be release as soon as possible. - apache1/2 The widely used HTTP server apache has several security vulnerabilities: - locally exploitable buffer overflow in the regular expression code. The attacker must be able to modify .htaccess or httpd.conf. (affects: mod_alias and mod_rewrite) - under some circumstances mod_cgid will output its data to the wrong client (affects: apache2) - proftpd A remote denial-of-service attack in the FTP server proftpd was fixed. The denial-of-service can be triggered by a one-byte buffer overflow with a fixed character. Therefore the bug can not be abused by an attacker to execute arbitrary code. If the binary is compiled with version 3.x of gcc this bug may not even lead to denial-of-service condition due to stack alignment. Update packages are available on our FTP servers. - gdm2 Two remote denial-of-service attacks were fixed in GDM. Update packages are available on our FTP servers. - epic/epic4 The well known IRC client epic can probably be exploited remotely by a malicious server. Update packages are available on our FTP servers. ______________________________________________________________________________ 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 un-installed 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 top-level 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. Only SUSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: hylafax Announcement-ID: SuSE-SA:2003:045 Date: Mon Nov 10 15:00:00 CET 2003 Affected products: 7.3, 8.0, 8.1, 8.2, 9.0 SuSE Linux Enterprise Server 7 SuSE Linux Standard Server 8 SuSE Linux Desktop 1.0 SuSE Linux Office Server Vulnerability Type: remote code execution Severity (1-10): 5 SUSE default package: No Cross References: CAN-2003-0886 http://www.hylafax.org Content of this advisory: 1) security vulnerability resolved: Format bug condition in hfaxd. problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - ethereal - KDE - sane - ircd - mc - apache1/2 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Hylafax is an Open Source fax server which allows sharing of fax equipment among computers by offering its service to clients by a protocol similar to FTP. The SuSE Security Team found a format bug condition during a code review of the hfaxd server. It allows remote attackers to execute arbitrary code as root. However, the bug can not be triggered in hylafax' default configuration. The "capi4hylafax" packages also need to be updated as a dependency where they are available. After the update has been successfully applied the hfaxd server has to be restarted by issuing the following command as root: /etc/rc.d/hylafax restart 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.

These packages fixes several vulnerabilities: + remote root compromise (CAN-2003-0690) + weak cookies (CAN-2003-0692) + SSL man-in-the-middle attack + information leak through HTML-referrer (CAN-2003-0459) The packages will be release as soon as testing is finished. - sane The scanner service sane of SuSE Linux 7.3-8.1 is vulnerable to a remote denial-of-service attack. This attack can even be triggered if the attackers host is not listed in the saned.conf file. The packages are currently tested and will be release as soon as possible. - ircd The Internet Relay Chat daemon is vulnerable to a remote denial-of- service attack. The attack can be triggered by irc clients directly connected to the daemon. The packages are currently tested and will be release as soon as possible. - mc By using a special combination of links in archive-files it is possible to execute arbitrary commands while mc tries to open it in its VFS. The packages are currently tested and will be release as soon as possible. - apache1/2 The widely used HTTP server apache has several security vulnerabilities: - locally exploitable buffer overflow in the regular expression code. The attacker must be able to modify .htaccess or httpd.conf. (affects: mod_alias and mod_rewrite) - under some circumstances mod_cgid will output its data to the wrong client (affects: apache2) ______________________________________________________________________________ 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 un-installed 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 top-level 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. Only SUSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info(a)suse.com> or <suse-security-faq(a)suse.com> respectively. ===================================================================== SUSE's security contact is <security(a)suse.com> or <security(a)suse.de>.
