New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7

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)
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.
