3. Description:
Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.
Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (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.
All Firefox users should upgrade to these updated packages, which contain
Firefox version 38.6.0 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
