GLSA-200505-09 : Gaim: Denial of Service and buffer overflow vulnerabilties
High Nessus Plugin ID 18252
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200505-09 (Gaim: Denial of Service and buffer overflow vulnerabilties)
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.
SolutionAll Gaim users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-im/gaim-1.3.0'
