Severity: High Title: Gaim: Denial of Service and buffer overflow vulnerabilties Date: May 12, 2005 Bugs: #91862 ID: 200505-09

Synopsis ========
Gaim contains two vulnerabilities, potentially resulting in the execution of arbitrary code or Denial of Service.
Background ==========
Gaim is a full featured instant messaging client which handles a variety of instant messaging protocols.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-im/gaim < 1.3.0 >= 1.3.0
Description ===========
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).
Impact ======
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.
Workaround ==========
There are no known workarounds at this time.
Resolution ==========
All Gaim users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-im/gaim-1.3.0"
