Red Hat: 2015:1012-01: thunderbird: Important Advisory
Summary
Mozilla Thunderbird is a standalone mail and newsgroup client.
Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Thunderbird to crash or,
potentially, execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2015-2708, CVE-2015-2710, CVE-2015-2713)
A heap-based buffer overflow flaw was found in the way Thunderbird
processed compressed XML data. An attacker could create specially crafted
compressed XML content that, when processed by Thunderbird, could cause it
to crash or execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2015-2716)
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.
Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Jesse Ruderman, Mats Palmgren, Byron Campen, Steve
Fink, Atte Kettunen, Scott Bell, and Ucha Gobejishvili as the original
reporters of these issues.
For technical details regarding these flaws, refer to the Mozilla security
advisories for Thunderbird 31.7. 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 31.7, which corrects these issues.
After installing the update, Thunderbird must be restarted for the changes
to take effect.
