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: SRPMS: ftp://updates.redhat.com/9/en/os/SRPMS/xchat-1.8.11-9.src.rpm i386: ftp://updates.redhat.com/9/en/os/i386/xchat-1.8.11-9.i386.rpm 6.
