3. Description:

 

Mozilla Thunderbird is a standalone mail and newsgroup client.

 

A flaw was found in the way Thunderbird handled security wrappers.

Malicious content could cause Thunderbird to execute arbitrary code with

the privileges of the user running Thunderbird. (CVE-2012-4193)

 

Red Hat would like to thank the Mozilla project for reporting this issue.

Upstream acknowledges moz_bug_r_a4 as the original reporter.

 

Note: This issue cannot be exploited by a specially-crafted HTML mail

message as JavaScript is disabled by default for mail messages. It could be

exploited another way in Thunderbird, for example, when viewing the full

remote content of an RSS feed.

 

All Thunderbird users should upgrade to this updated package, which

corrects this issue. After installing the update, Thunderbird must be

restarted for the changes to take effect.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to

use the Red Hat Network to apply this update are available at
