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" References ========== [ 1 ] CAN-2005-1261 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1261 [ 2 ] CAN-2005-1262 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1262 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-09.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
