Synopsis: Critical: xulrunner security update
Issue Date: 2012-02-16
CVE Numbers: CVE-2011-3026
XULRunner provides the XUL Runtime environment for applications using the
Gecko layout engine.
A heap-based buffer overflow flaw was found in the way XULRunner handled
PNG (Portable Network Graphics) images. A web page containing a malicious
PNG image could cause an application linked against XULRunner (such as
Firefox) to crash or, potentially, execute arbitrary code with the
privileges of the user running the application. (CVE-2011-3026)
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.
