Red Hat Security Advisory
Synopsis: An updated X-Chat package fixes vulnerability in Socks-5 proxy 1. Topic: An updated X-Chat package fixes a vulnerability which could be exploited by a malicious Socks-5 proxy is now available. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 3. Problem description: X-Chat is a graphical IRC chat client for the X Window System. A stack buffer overflow flaw was found in the X-Chat's Socks-5 proxy code. An attacker could create a malicious Socks-5 proxy server in such a way that X-Chat would execute arbitrary code if a victim configured X-Chat to use the proxy. Users of X-Chat should upgrade to this updated package which contains a backported security patch and is not vulnerable to this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory only contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://rhn.redhat.com/help/latest-up2date.pxt 5. RPMs required: Red Hat Linux 9:

Synopsis: Updated httpd packages fix mod_ssl security issue 1. Topic: Updated httpd packages are now available that fix a denial of service vulnerability in mod_ssl and include various other bug fixes. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 3. Problem description: The Apache HTTP server is a powerful, full-featured, efficient, and freely-available Web server. A memory leak in mod_ssl in the Apache HTTP Server prior to version 2.0.49 allows a remote denial of service attack against an SSL-enabled server. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2004-0113 to this issue. Users of the Apache HTTP server should upgrade to these updated packages, which contain backported patches that address these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory only contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.

Synopsis: An updated LHA package fixes security vulnerabilities 1. Topic: An updated LHA package that fixes several security vulnerabilities is now available. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 3. Problem description: LHA is an archiving and compression utility for LHarc format archives. Ulf Harnhammar discovered two stack buffer overflows and two directory traversal flaws in LHA. An attacker could exploit the buffer overflows by creating a carefully crafted LHA archive in such a way that arbitrary code would be executed when the archive is tested or extracted by a victim. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2004-0234 to this issue. An attacker could exploit the directory traversal issues to create files as the victim outside of the expected directory. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2004-0235 to this issue. Users of LHA should update to this updated packages which contain backported patches not vulnerable to these issues. Red Hat would like to thank Ulf Harnhammar for disclosing and providing test cases and patches for these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated.
