Description

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-2015-7201, CVE-2015-7205, CVE-2015-7212, CVE-2015-7213)

A flaw was found in the way Thunderbird handled content using the 'data:'
and 'view-source:' URIs. An attacker could use this flaw to bypass the
same-origin policy and read data from cross-site URLs and local files.
(CVE-2015-7214)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Andrei Vaida, Jesse Ruderman, Bob Clary, Abhishek
Arya, Ronald Crane, and Tsubasa Iinuma as the original reporters of these
issues.

For technical details regarding these flaws, refer to the Mozilla security
advisories for Thunderbird 38.5.0. 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 38.5.0, which corrects these issues. After
installing the update, Thunderbird must be restarted for the changes to
take effect.
