Background ========== Valgrind is an open-source memory debugger. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-util/valgrind < 3.4.0 >= 3.4.0 Description =========== Tavis Ormandy reported that Valgrind loads a .valgrindrc file in the current working directory, executing commands specified there. Impact ====== A local attacker could prepare a specially crafted .valgrindrc file and entice a user to run Valgrind from the directory containing that file, resulting in the execution of arbitrary code with the privileges of the user running Valgrind. Workaround ========== Do not run "valgrind" from untrusted working directories. Resolution ========== All Valgrind users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-util/valgrind-3.4.0" References ========== [ 1 ] CVE-2008-4865 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4865 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200902-03.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.
