Description Huzaifa S. Sidhpurwala 2014-07-21 04:41:09 UTC
Using the Address Sanitizer tool, security researcher Atte Kettunen from OUSPG discovered a buffer overflow during interaction with the Web Audio buffer for playback because of an error in the the amount of allocated memory for buffers. This leads to a potentially exploitable crash with some audio content.

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.
