Background ========== zoo is a file archiving utility for maintaining collections of files, written by Rahul Dhesi. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/zoo < 2.10-r1 >= 2.10-r1 Description =========== Jean-Sebastien Guay-Leroux discovered a boundary error in the fullpath() function in misc.c when processing overly long file and directory names in ZOO archives. Impact ====== An attacker could craft a malicious ZOO archive and entice someone to open it using zoo. This would trigger a stack-based buffer overflow and potentially allow execution of arbitrary code with the rights of the victim user. Workaround ========== There is no known workaround at this time. Resolution ========== All zoo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r1" References ========== [ 1 ] CVE-2006-0855 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0855 [ 2 ] Original Advisory http://www.guay-leroux.com/projects/zoo-advisory.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200603-05.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.
