Title: Gaim: Denial of Service and buffer overflow vulnerabilties (GLSA 200505-09)
Date: May 12, 2005
Gaim contains two vulnerabilities, potentially resulting in the execution of arbitrary code or Denial of Service.
Gaim is a full featured instant messaging client which handles a variety of instant messaging protocols.
Vulnerable: < 1.3.0
Unaffected: >= 1.3.0
Architectures: All supported architectures
Stu Tomlinson discovered that Gaim is vulnerable to a remote stack based buffer overflow when receiving messages in certain protocols, like Jabber and SILC, with a very long URL (CAN-2005-1261). Siebe Tolsma discovered that Gaim is also vulnerable to a remote Denial of Service attack when receiving a specially crafted MSN message (CAN-2005-1262).
A remote attacker could cause a buffer overflow by sending an instant message with a very long URL, potentially leading to the execution of malicious code. By sending a SLP message with an empty body, a remote attacker could cause a Denial of Service or crash of the Gaim client.
There are no known workarounds at this time.
All Gaim users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/gaim-1.3.0"
