"An update for thunderbird is now available for Red Hat Enterprise
Linux 5, Red Hat Enterprise Linux 6, and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Mozilla Thunderbird is a standalone mail and newsgroup client.

This update upgrades Thunderbird to version 45.4.0.

Security Fix(es) :

* Multiple 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-2016-5257)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Christoph Diehl, Andrew McCreight, Dan
Minor, Byron Campen, Jon Coppeard, Steve Fink, Tyson Smith, Philipp
and Carsten Book as the original reporters."
