Background ========== unp is a script for unpacking various file formats. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/unp < 1.0.14 >= 1.0.14 Description =========== Erich Schubert from Debian discovered that unp does not escape file names properly before passing them to calls of the shell. Impact ====== A remote attacker could entice a user or automated system to unpack a compressed archive with a specially crafted file name, leading to the execution of shell commands from within the filename. That code will be executed with the privileges of the user running unp. Workaround ========== There is no known workaround at this time. Resolution ========== All unp users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/unp-1.0.14" References ========== [ 1 ] CVE-2007-6610 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6610 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200801-01.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.
