Background ========== RAR and UnRAR provide command line interfaces for compressing and decompressing RAR files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/rar < 3.7.0_beta1 >= 3.7.0_beta1 2 app-arch/unrar < 3.7.3 >= 3.7.3 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== RAR and UnRAR contain a boundary error when processing password-protected archives that could result in a stack-based buffer overflow. Impact ====== A remote attacker could entice a user to process a specially crafted password-protected archive and execute arbitrary code with the rights of the user uncompressing the archive. Workaround ========== There is no known workaround at this time. Resolution ========== All UnRAR users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/rar-3.7.3" All RAR users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/rar-3.7.0_beta1" References ========== [ 1 ] CVE-2007-0855 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0855 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200702-04.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.
