Background ========== KVIrc is a free portable IRC client based on Qt. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-irc/kvirc < 3.2.6_pre20070714 >= 3.2.6_pre20070714 Description =========== Stefan Cornelius from Secunia Research discovered that the "parseIrcUrl()" function in file src/kvirc/kernel/kvi_ircurl.cpp does not properly sanitise parts of the URI when building the command for KVIrc's internal script system. Impact ====== A remote attacker could entice a user to open a specially crafted irc:// URI, possibly leading to the remote execution of arbitrary code with the privileges of the user running KVIrc. Successful exploitation requires that KVIrc is registered as the default handler for irc:// or similar URIs. Workaround ========== There is no known workaround at this time. Resolution ========== All KVIrc users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-irc/kvirc-3.2.6_pre20070714" References ========== [ 1 ] CVE-2007-2951 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2951 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200709-02.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.
