Summary
Red Hat Security Advisory: : Updated Gaim packages fix various vulnerabiliies

Notes

Topic
Updated Gaim packages that fix a number of serious vulnerabilities are now available.
Details
Gaim is an instant messenger client that can handle multiple protocols. Stefan Esser audited the Gaim source code and found a number of bugs that have security implications. Due to the nature of instant messaging many of these bugs require man-in-the-middle attacks between client and server. However at least one of the buffer overflows could be exploited by an attacker sending a carefully-constructed malicious message through a server. The issues include: Multiple buffer overflows that affect versions of Gaim 0.75 and earlier. 1) When parsing cookies in a Yahoo web connection, 2) YMSG protocol overflows parsing the Yahoo login webpage, 3) a YMSG packet overflow, 4) flaws in the URL parser, and 5) flaws in HTTP Proxy connect. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0006 to these issues. A buffer overflow in Gaim 0.74 and earlier in the Extract Info Field Function used for MSN and YMSG protocol handlers. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0007 to this issue. An integer overflow in Gaim 0.74 and earlier, when allocating memory for a directIM packet results in heap overflow. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0008 to this issue. All users of Gaim should upgrade to these erratum packages, which contain backported security patches correcting these issues. Red Hat would like to thank Steffan Esser for finding and reporting these issues and Jacques A. Vidrine for providing initial patches.
