- --------------------------------------------------------------------- 1. Summary: An updated gaim package that fixes various security issues as well as a number of bugs is now available. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Problem description: The Gaim application is a multi-protocol instant messaging client. Two HTML parsing bugs were discovered in Gaim. It is possible that a remote attacker could send a specially crafted message to a Gaim client, causing it to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-0208 and CAN-2005-0473 to these issues. A bug in the way Gaim processes SNAC packets was discovered. It is possible that a remote attacker could send a specially crafted SNAC packet to a Gaim client, causing the client to stop responding. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0472 to this issue. Additionally, various client crashes, memory leaks, and protocol issues have been resolved. Users of Gaim are advised to upgrade to this updated package which contains Gaim version 1.1.4 and is not vulnerable to these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages.
