Description Huzaifa S. Sidhpurwala 2013-09-18 01:59:27 UTC 
Using the Address Sanitizer tool, security researcher Atte Kettunen from OUSPG found that the HTML5 Tree Builder does not properly store state when interacting with template elements. Because some stack information is incorrectly stored, the template insertion mode stack can be used when it is empty. This could possibly lead to code execution in some circumstances.

In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
