Scientific Linux Security Update : xulrunner on SL5.x, SL6.x i386/x86_64
High Nessus Plugin ID 61253
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionXULRunner 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.
SolutionUpdate the affected xulrunner, xulrunner-debuginfo and / or xulrunner-devel packages.
