(RHSA-2013:0614) Critical: xulrunner security update

XULRunner provides the XUL Runtime environment for applications using the
Gecko layout engine.

A flaw was found in the way XULRunner handled malformed web content. A web
page containing malicious content could cause an application linked against
XULRunner (such as Mozilla Firefox) to crash or execute arbitrary code with
the privileges of the user running the application. (CVE-2013-0787)

Red Hat would like to thank the Mozilla project for reporting this issue.
Upstream acknowledges VUPEN Security via the TippingPoint Zero Day
Initiative project as the original reporter.

For technical details regarding this flaw, refer to the Mozilla security
advisories. You can find a link to the Mozilla advisories in the References
section of this erratum.

All XULRunner users should upgrade to these updated packages, which correct
this issue. After installing the update, applications using XULRunner must
be restarted for the changes to take effect.
