Oracle Linux 5 / 6 : libexif (ELSA-2012-1255)
High Nessus Plugin ID 68615
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2012:1255 :
Updated libexif packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
The libexif packages provide an Exchangeable image file format (Exif) library. Exif allows metadata to be added to and read from certain types of image files.
Multiple flaws were found in the way libexif processed Exif tags. An attacker could create a specially crafted image file that, when opened in an application linked against libexif, could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-2812, CVE-2012-2813, CVE-2012-2814, CVE-2012-2836, CVE-2012-2837, CVE-2012-2840, CVE-2012-2841)
