Gaim is a multi-protocol instant messaging client for Linux which supports many instant messaging protocols.
Sebastian Krahmer of the SuSE Security Team has discovered a remotely exploitable buffer overflow vulnerability in the code handling MSN protocol parsing.
By sending a carefully-crafted message, an attacker may execute arbitrary code with the permissions of the user running Gaim.
There is no known workaround at this time. All users are encouraged to upgrade to the latest available version of Gaim.
All Gaim users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=net-im/gaim-0.81-r1"
# emerge ">=net-im/gaim-0.81-r1"
