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 < 1.5.0 >= 1.5.0 Description =========== Brandon Perry discovered that Gaim is vulnerable to a heap-based buffer overflow when handling away messages (CAN-2005-2103). Furthermore, Daniel Atallah discovered a vulnerability in the handling of file transfers (CAN-2005-2102). Impact ====== A remote attacker could create a specially crafted away message which, when viewed by the target user, could lead to the execution of arbitrary code. Also, an attacker could send a file with a non-UTF8 filename to a user, which would result in a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All Gaim users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-im/gaim-1.5.0" References ========== [ 1 ] CAN-2005-2102 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2102 [ 2 ] CAN-2005-2103 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2103 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200508-06.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.
