Background ========== libexif is a library for parsing, editing and saving EXIF data. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libexif < 0.5.12-r1 >= 0.5.12-r1 Description =========== libexif contains a buffer overflow vulnerability in the EXIF tag validation code. When opening an image with a specially crafted EXIF tag, the lack of validation can cause applications linked to libexif to crash. Impact ====== A specially crafted EXIF file could crash applications making use of libexif, potentially allowing 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 libexif users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libexif-0.5.12-r1" References ========== [ 1 ] CAN-2005-0664 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0664 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200503-17.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.
