SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated openjpeg packages that fix two security issues are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having important 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.
OpenJPEG is an open source library for reading and writing image files in JPEG 2000 format.
An input validation flaw, leading to a heap-based buffer overflow, was found in the way OpenJPEG handled the tile number and size in an image tile header. A remote attacker could provide a specially crafted image file that, when decoded using an application linked against OpenJPEG, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-3358)
OpenJPEG allocated insufficient memory when encoding JPEG 2000 files from input images that have certain color depths. A remote attacker could provide a specially crafted image file that, when opened in an application linked against OpenJPEG (such as image_to_j2k), would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
Users of OpenJPEG should upgrade to these updated packages, which contain patches to correct these issues. All running applications using OpenJPEG must be restarted for the update to take effect.
SolutionUpdate the affected openjpeg packages.
