Background ========== GNU tar is the standard GNU utility for creating and manipulating tar archives, a common format used for creating backups and distributing files on UNIX-like systems. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/tar < 1.15.1-r1 >= 1.15.1-r1 Description =========== Jim Meyering discovered a flaw in the handling of certain header fields that could result in a buffer overflow when extracting or listing the contents of an archive. Impact ====== A remote attacker could construct a malicious tar archive that could potentially execute arbitrary code with the privileges of the user running GNU tar. Workaround ========== There is no known workaround at this time. Resolution ========== All GNU tar users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/tar-1.15.1-r1" References ========== [ 1 ] CVE-2006-0300 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0300 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200603-06.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.
