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-2015-4500, CVE-2015-4509, CVE-2015-4510)

 

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

Upstream acknowledges Andrew Osmond, Olli Pettay, Andrew Sutherland,

Christian Holler, David Major, Andrew McCreight, Cameron McCormack, and

Looben Yang as the original reporters of these issues.

 

All Firefox users should upgrade to these updated packages, which contain

Firefox version 38.3.0 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.

 

For details on how to apply this update, refer to:
