Background ========== GNU cpio copies files into or out of a cpio or tar archive. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/cpio < 2.9-r1 >= 2.9-r1 Description =========== A buffer overflow vulnerability in the safer_name_suffix() function in GNU cpio has been discovered. Impact ====== A remote attacker could entice a user to open a specially crafted archive file resulting in a stack-based buffer overflow, possibly crashing the application. It is disputed whether the execution of arbitrary code is possible. Workaround ========== There is no known workaround at this time. Resolution ========== All GNU cpio users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/cpio-2.9-r1" References ========== [ 1 ] CVE-2007-4476 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4476 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200711-18.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.
