| Description: | 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.
