The remote Red Hat host is missing one or more security updates.
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.
JasPer is an implementation of Part 1 of the JPEG 2000 image
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.
