Background ========== CVS (Concurrent Versions System) is an open-source network-transparent version control system. It contains both a client utility and a server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-util/cvs < 1.11.18-r1 >= 1.11.18-r1 Description =========== Alen Zukich has discovered several serious security issues in CVS, including at least one buffer overflow (CAN-2005-0753), memory leaks and a NULL pointer dereferencing error. Impact ====== An attacker could exploit these vulnerabilities to cause a Denial of Service or execute arbitrary code with the permissions of the CVS pserver or the authenticated user (depending on the connection method used). Workaround ========== There is no known workaround at this time. Resolution ========== All CVS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-util/cvs-1.11.18-r1" References ========== [ 1 ] CAN-2005-0753 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0753 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200504-16.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.
