Stefan Esser found 12 vulnerabilities in gaim that can lead to a remote system compromise with the privileges of the user running GAIM. The GAIM package that SUSE LINUX ships is affected by just twoof these bug: - Yahoo Packet Parser Overflow - HTTP Proxy Connect Overflow The first vulnerability is easy to exploit and results in a classic stack overflow which can be used to execute arbitrary code. The latter vulnerability requires the gaim client use a HTTP proxy under the control of the attacker. The exploitation of this bug results in arbitrary code execution too. There is no known workaround. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, to apply the update use the command "rpm -Fhv file.rpm". Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. Intel i386 Platform: SuSE-9.0: 09f8d12dd52e246cf32dca8ad3374f39 patch rpm(s): 3a633e341b9e56facdbe0250b55dd33a source rpm(s): 5ee6a86077c0297a64815532782f7a54 SuSE-8.2: 7a269744304f72bf951c7bd6974560f2 patch rpm(s): e7b18f0da02c1c4392dc1b03e835a827 source rpm(s): ae7d7b1c9735696244547a0d6a5ee92e SuSE-8.1: 22b1d4be5737906f8ff0975918279034 patch rpm(s): 7644020869e92cc980b881efebf9d617 source rpm(s): cd1532f71a79ed32d016d456a844ff4b SuSE-8.0: 7dcb581b78bf8ab61e82bf0836a4357e patch rpm(s): 5a6f596538edc56e0b3a70a23200c21e source rpm(s): d38c8da629941eecef7f75d6a5ea9e80 ______________________________________________________________________________ 2) Pending vulnerabilities in SUSE Distributions and Workarounds: - kernel binaries for SLES8 AMD64 Due to a human failure the kernel binaries of SuSE Linux Enterprise Server 8 for AMD64 lack the fix described in SuSE-SA:2004:003. The kernel-source packages and the packages for IA64 are *not* affected. New packages are available at our maintenance-web. - mc By using a specialcombination of links in archive files it is possible to execute arbitrary commands while mc tries to open it in its VFS. New packages are available on our FTP servers. - mod_gzip (apache-contrib) 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. Additionally the mod_gzip code was audited to fix more possibly security related bugs. After more testing a new apache-contrib RPM package will be released. - tripwire Tripwire is a file integrity checker. The version of tripwire included with SuSE Linux 9.0 crashs when a requested file does not exists. New packages are available on our FTP servers. - XDM (XFree86, xf86) A missing check for failure conditions in the PAM code of XDM can lead to local root access in conjunction with Kerberos or other authentication methods. New packages are available on our FTP servers. - 3ddiag Some 3ddiag scripts handle temporary files in an insecure manner. Thanks to Stefan Nordhausen for reporting some of these issues. New packages are available on our FTP servers. - mod_auth_shadow (apache-contrib) This apache module ignores account expiration dates. The update will be released together with mod_gzip. - cvsup cvsup uses a library path which is world-writeable. This behavior can lead to local privilege escalation. Thanks to Matthias Andree for notifying us. Upcoming SuSE Linux versions have an automatic check enabled to detect these types of bugs. New packages are available on our FTP servers. - nmap Due to a bad interaction between kernel and user-space for pre- calculated IP checksums nmap did not work on SUSE LINUX 9.0. New packages are available on our FTP servers. - netpbm Some tools in the netpbm suite create files in an insecure manner that can lead to local privilege escalation. New packages will be available soon. - zebra Local users can send malicious netlink messages that cause denial-of-service conditions in zebra. New packages will be available soon. - quagga Local users can send malicious netlink messages that cause denial-of-service conditions in the routing-daemon quagga. New packages are available on our FTP servers. - tcpdump The code for handling ISAKMP and RADIUS messages contained bugs which allowed remote attackers to crash tcpdump or to execute arbitrary code. New packages are available on our FTP servers. - mod_python A remote denial-of-service attack can be triggered against the Apache web server by sending a specific query string that is processed by mod_python. New packages will be available soon. ______________________________________________________________________________ 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 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

There are multiple vulnerabilities in hypermail.. ______________________________________________________________________________ SuSE Security Announcement Package: hypermail Announcement-ID: SuSE-SA:2003:0012 Date: Thursday, Feb 27th 2003 18:30 MET Affected products: 7.1, 7.2, 7.3, 8.0, 8.1 Vulnerability Type: remote system compromise Severity (1-10): 4 SuSE default package: no Cross References: CAN-2003-0025 Content of this advisory: 1) security vulnerability resolved: several bugs after source code review problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - vnc - w3m 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Hypermail is a tool to convert a Unix mail-box file to a set of cross- referenced HTML documents. During an internal source code review done by Thomas Biege several bugs where found in hypermail and its tools. These bugs allow remote code execution, local tmp race conditions, denial-of-service conditions and read access to files belonging to the host hypermail is running on. Additionally the mail CGI program can be abused by spammers as email- relay and should thus be disabled. There is no temporary fix known other then disabling hypermail. Please download and install the new packages from our FTP servers. 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 beingnotified individually.

Some SQL-injection vulnerabilities were found in IMP 2.x that allow an attacker to access the underlying database.. ______________________________________________________________________________ SuSE Security Announcement Package: imp Announcement-ID: SuSE-SA:2003:0008 Date: Tuesday, Feb. 18th 2003 18:20 MET Affected products: 7.3, 8.0, 8.1 Vulnerability Type: remote system compromise Severity (1-10): 3 SuSE default package: no Cross References: CAN-2003-0025 Content of this advisory: 1) security vulnerability resolved: Multiple SQL-Injection problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - mod_php4 - libmcrypt - vim - pam_xauth - openldap2 - mpg123 - syslinux 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information IMP is a well known PHP-based web-mail system. Some SQL-injection vulnerabilities were found in IMP 2.x that allow an attacker to access the underlying database. No authentication is needed to exploit this bug. An attacker can gain access to protected information or, in conjunction with PostgreSQL, execute shell commands remotely. There is no temporary fix known. Please install the new packages from our FTP servers. 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 maintenanceweb. Intel i386 Platform: SuSE-8.1: 17b26d9e48a75cc499b6d4da0c1067c3 source rpm(s): 6e3e250a900070b1571f8f3b050616a8 SuSE-8.0: d50ed25aecc357a720f901676a399def source rpm(s): 7e9fcc065b3096fc7f40f1c958ea9b0b SuSE-7.3: bf74d9df4b7e9b02d922609c226cff92 source rpm(s): b858c113f66145fdc38d6629b1dbafb8 Sparc Platform: SuSE-7.3: b0bf87d69dfcd8aae2ec3d3a07d14899 source rpm(s): bd236d18ab61c67fe4929be6ff7fa82a AXP Alpha Platform: PPC Power PC Platform: SuSE-7.3: 0e186259b4441dd1347e4e5e6f14aac9 source rpm(s): 8688d0e39dae720267a568562a0548c3 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - mod_php4 A buffer overflow in the wordwrap() function has been reported. New packages will be prepared and should be available on our ftp servers soon. - libmcrypt Several buffer overflows in libmcrypt were discovered by Ilia Alshanetsky. The buffer overflows can lead to system compromise. New packages are currently being build. - vim Georgi Guninski reported a security problem with vim's modeline support that allows the execution of commands when a malformed file was opened. This bug may even be exploited through MUAs like mutt. We recommend to turn off this feature globally by adding the line: set modelines=0 to the global configuration file /etc/vimrc. All currently supported SuSE products are affected by this problem. Modeline support is disabled by default in future version of SuSE Linux. - openldap2 The BER decoding routines of the openldap2 packages for SL 8.1 and SLES8 contained a bug which allowed remote attackers to mount a DoS attack against vulnerable OpenLDAP servers. It is necessary to update the openldap2-devel, openldap2-client and openldap2 packages in order to prevent such attack. New packages will be available on our FTP servers soon. - mpg123 Our update directories on our ftp server for the SuSE Linux distributions 7.3, 8.0 and 8.1 contain update packages for the mpg123 package. These updates fix a security problem with mpg123 that can result in the execution of arbitrary commands upon playing a specially crafted mpeg audio layer 3 file. Other versions of SuSE Linux than mentioned above do not contain a vulnerable version of the mpg123 mp3 player. - pam_xauth SuSE Linux starting with version 7.2 contain a PAM (Pluggable Authentication Module) called pam_xauth which can be used to pass on X11-authentification data (cookies, see "man Xsecurity") if a user uses /bin/su to assume the privileges of another user. Since the possession of the X11 authentification cookie grants access to the running X-server and all of its resources, this should be considered a security problem if the feature cannot be turned off by a non-root user. The presence of the pam_xauth PAM does not represent a threat such if it is not enabled by default. By default, the pam_xauth module is not enabled in all SuSE products. We recommend to use the /usr/X11R6/bin/sux wrapper script for the su command that comes with SuSE products to pass on X11 authentification data if so desired intentionally by the user. - syslinux The syslinux bootloader has been found vulnerable to a not closely named security weakness by Dan Hollis if the bootloader program is installed setuid root. We do not believe that elevated privileges are beneficial for a bootloader. The packages in SuSE Linux are not vulnerable to the weakness. ______________________________________________________________________________ 3) standard appendix: authenticityverification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world.
