Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2013:1480 :

An updated thunderbird package that fixes several security issues is
now available for Red Hat Enterprise Linux 5 and 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.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed content.
Malicious content could cause Thunderbird to crash or, potentially,
execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2013-5590, CVE-2013-5597, CVE-2013-5599,
CVE-2013-5600, CVE-2013-5601, CVE-2013-5602)

It was found that the Thunderbird JavaScript engine incorrectly
allocated memory for certain functions. An attacker could combine this
flaw with other vulnerabilities to execute arbitrary code with the
privileges of the user running Thunderbird. (CVE-2013-5595)

A flaw was found in the way Thunderbird handled certain Extensible
Stylesheet Language Transformations (XSLT) files. An attacker could
combine this flaw with other vulnerabilities to execute arbitrary code
with the privileges of the user running Thunderbird. (CVE-2013-5604)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Jesse Ruderman, Christoph Diehl, Dan
Gohman, Byoungyoung Lee, Nils, and Abhishek Arya as the original
reporters of these issues.

Note: All of the above issues cannot be exploited by a
specially-crafted HTML mail message as JavaScript is disabled by
default for mail messages. They could be exploited another way in
Thunderbird, for example, when viewing the full remote content of an
RSS feed.

For technical details regarding these flaws, refer to the Mozilla
security advisories for Thunderbird 17.0.10 ESR. You can find a link
to the Mozilla advisories in the References section of this erratum.

All Thunderbird users should upgrade to this updated package, which
contains Thunderbird version 17.0.10 ESR, which corrects these issues.
After installing the update, Thunderbird must be restarted for the
changes to take effect.
