Description Huzaifa S. Sidhpurwala 2014-07-21 04:50:52 UTC 
Using the Address Sanitizer tool, security researcher Atte Kettunen from OUSPG discovered a use-after-free in Web Audio due to an issue with how control messages for Web Audio are ordered and processed. This leads to a potentially exploitable crash.

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.
