- Updated Gaim packages that fix a number of serious vulnerabilities are now
- available.
-
- 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.
