3. 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-2016-1930, CVE-2016-1935)

 

Red Hat would like to thank the Mozilla project for reporting these issues.

Upstream acknowledges Bob Clary, Christian Holler, Nils Ohlmeier, Gary

Kwong, Jesse Ruderman, Carsten Book, Randell Jesup, and Aki Helin as the

original reporters of these issues.

 

For technical details regarding these flaws, refer to the Mozilla security

advisories for Thunderbird 38.6.0. 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 38.6.0, which corrects these issues. After

installing the update, Thunderbird must be restarted for the changes to

take effect.
