Background ========== CenterICQ is a text-based instant messaging interface that supports multiple protocols. It includes the ktools library, which provides text-mode user interface controls. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-im/centericq < 4.21.0-r2 >= 4.21.0-r2 Description =========== Gentoo developer Wernfried Haas discovered that when the "Enable peer-to-peer communications" option is enabled, CenterICQ opens a port that insufficiently validates whatever is sent to it. Furthermore, Zone-H Research reported a buffer overflow in the ktools library. Impact ====== A remote attacker could cause a crash of CenterICQ by sending packets to the peer-to-peer communications port, and potentially cause the execution of arbitrary code by enticing a CenterICQ user to edit overly long contact details. Workaround ========== There is no known workaround at this time. Resolution ========== All CenterICQ users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-im/centericq-4.21.0-r2" References ========== [ 1 ] CVE-2005-3694 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3694 [ 2 ] CVE-2005-3863 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3863 [ 3 ] Zone-H Research ZRCSA 200503 http://www.zone-h.org/en/advisories/read/id=8480/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200512-11.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. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
