Vulnerability Instance

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.
