Description

Daniel Atallah discovered a Denial of Service vulnerability in the file transfer handler of OSCAR (the module that handles various instant messaging protocols like ICQ). A remote attacker could crash the Gaim client of an user by attempting to send him a file with a name that contains invalid UTF-8 characters. (CAN-2005-2102)

It was found that specially crafted 'away' messages triggered a buffer overflow. A remote attacker could exploit this to crash the Gaim client or possibly even execute arbitrary code with the permissions of the Gaim user. (CAN-2005-2103)

Szymon Zygmunt and Michal Bartoszkiewicz discovered a memory alignment error in the Gadu library, which was fixed in USN-162-1. However, it was discovered that Gaim contains a copy of the vulnerable code. By sending specially crafted messages over the Gadu protocol, a remote attacker could crash Gaim. (CAN-2005-2370).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
