RHSA-2005:627 - Security Advisory

Topic

An updated gaim package that fixes multiple security issues is now available.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Description

Gaim is an Internet Messaging client.

A heap based buffer overflow issue was discovered in the way Gaim processes
away messages. A remote attacker could send a specially crafted away
message to a Gaim user logged into AIM or ICQ that could result in
arbitrary code execution. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-2103 to this issue.

Daniel Atallah discovered a denial of service issue in Gaim. A remote
attacker could attempt to upload a file with a specially crafted name to a
user logged into AIM or ICQ, causing Gaim to crash. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-2102 to this issue.

A denial of service bug was found in Gaim's Gadu Gadu protocol handler. A
remote attacker could send a specially crafted message to a Gaim user
logged into Gadu Gadu, causing Gaim to crash. Please note that this issue
only affects PPC and IBM S/390 systems running Gaim. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-2370 to this issue.

Users of gaim are advised to upgrade to this updated package, which
contains backported patches and is not vulnerable to these issues.
