Red Hat Bugzilla – Bug 1023845
CVE-2013-5603 Mozilla: Use-after-free in HTML document templates (MFSA 2013-102)
Last modified: 2016-03-04 06:49:17 EST
Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team used the Address Sanitizer tool to discover a user-after-free when interacting with HTML document templates. This leads to a potentially exploitable crash.
In general this flaw cannot be exploited through email in the Thunderbird and Seamonkey products because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Abhishek Arya as the original reporter.
This issue does not affect the version of firefox and thunderbird as shipped with Red Hat Enterprise Linux 5 and 6
