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 <= 1.11.16-r1 >= 1.11.17 Description =========== A team audit of the CVS source code performed by Stefan Esser and Sebastian Krahmer resulted in the discovery of several remotely exploitable vulnerabilities including: * no-null-termination of "Entry" lines * error_prog_name "double-free()" * Argument integer overflow * serve_notify() out of bounds writes Impact ====== An attacker could use these vulnerabilities to cause a Denial of Service or execute arbitrary code with the permissions of the user running cvs. Workaround ========== There is no known workaround at this time. All users are advised to upgrade to the latest available version of CVS. Resolution ========== All CVS users should upgrade to the latest stable version: # emerge sync # emerge -pv ">=dev-util/cvs-1.11.17" # emerge ">=dev-util/cvs-1.11.17" References ========== [ 1 ] E-matters Advisory 09/2004 http://security.e-matters.de/advisories/092004.html [ 2 ] CAN-2004-0414 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0414 [ 3 ] CAN-2004-0416 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0416 [ 4 ] CAN-2004-0417 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0417 [ 5 ] CAN-2004-0418 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0418 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200406-06.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.
