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-vcs/cvs < 1.12.12-r12 >= 1.12.12-r12 Description =========== It was discovered that when CVS is configured to use SSH for remote repositories it allows remote attackers to execute arbitrary code through a repository URL with a specially crafted hostname. Impact ====== A remote attacker, by enticing a user to clone a specially crafted repository, could possibly execute arbitrary code with the privileges of the process. 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-vcs/cvs-1.12.12-r12" References ========== [ 1 ] CVE-2017-12836 https://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-12836 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201709-17 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.
