Red Hat: 2012:0142-01: firefox: Critical Advisory
Summary
Mozilla Firefox is an open source web browser.
A heap-based buffer overflow flaw was found in the way Firefox handled
PNG (Portable Network Graphics) images. A web page containing a malicious
PNG image could cause Firefox to crash or, possibly, execute arbitrary
code with the privileges of the user running Firefox. (CVE-2011-3026)
All Firefox users should upgrade to this updated package, which corrects
this issue. After installing the update, Firefox must be restarted for the
changes to take effect.
