Background ========== cpio is a file archival tool which can also read and write tar files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/cpio < 2.6-r3 >= 2.6-r3 Description =========== A vulnerability has been found in cpio that can potentially allow a cpio archive to extract its files to an arbitrary directory of the creator's choice. Impact ====== An attacker could create a malicious cpio archive which would create files in arbitrary locations on the victim's system. This issue could also be used in conjunction with a previous race condition vulnerability (CAN-2005-1111) to change permissions on files owned by the victim. Workaround ========== There is no known workaround at this time. Resolution ========== All cpio users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/cpio-2.6-r3" References ========== [ 1 ] Original Advisory http://www.securityfocus.com/archive/1/396429 [ 2 ] CAN-2005-1111 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1111 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200506-16.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. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
