Synopsis

Important: jasper security update

Type/Severity

Security Advisory: Important

Topic

Updated jasper 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.

Description

JasPer is an implementation of Part 1 of the JPEG 2000 image compression
standard.

Two heap-based buffer overflow flaws were found in the way JasPer decoded
JPEG 2000 compressed image files. An attacker could create a malicious JPEG
2000 compressed image file that, when opened, would cause applications that
use JasPer (such as Nautilus) to crash or, potentially, execute arbitrary
code. (CVE-2011-4516, CVE-2011-4517)

Red Hat would like to thank Jonathan Foote of the CERT Coordination Center
for reporting these issues.

Users are advised to upgrade to these updated packages, which contain a
backported patch to correct these issues. All applications using the JasPer
libraries (such as Nautilus) must be restarted for the update to take
effect.
