=========================================================== Ubuntu Security Notice USN-168-1 August 12, 2005 gaim vulnerabilities CAN-2005-2102, CAN-2005-2103, CAN-2005-2370 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) Ubuntu 5.04 (Hoary Hedgehog) The following packages are affected: gaim The problem can be corrected by upgrading the affected package to version 1:1.0.0-1ubuntu1.8 (for Ubuntu 4.10), or 1:1.1.4-1ubuntu4.4 (for Ubuntu 5.04). After performing a standard system upgrade you need to restart Gaim to effect the necessary changes. Details follow: 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 Michał 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)
