Background ========== E2fsprogs provides utilities for use with the ext2 and ext3 file systems including the libext2fs library that allows user-level programs to manipulate an ext2 or ext3 file system. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-fs/e2fsprogs < 1.40.3 >= 1.40.3 Description =========== Rafal Wojtczuk (McAfee AVERT Research) discovered multiple integer overflows in libext2fs, that are triggered when processing information from within the file system, resulting in heap-based buffer overflows. Impact ====== An attacker could entice a user to process a specially-crafted ext2 or ext3 file system image (with tools linking against libext2fs, e.g. fsck, forensic tools or Xen's pygrub), possibly resulting in the execution of arbitrary code with the privileges of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All E2fsprogs users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-fs/e2fsprogs-1.40.3" References ========== [ 1 ] CVE-2007-5497 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5497 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200712-13.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.
