Description Huzaifa S. Sidhpurwala 2013-04-01 02:03:49 UTC
Security researcher miaubiz used the Address Sanitizer tool to discover a crash in WebGL rendering when memory is freed that has not previously been allocated. This issue only affects Linux users who have Intel Mesa graphics drivers. The resulting crash could be potentially exploitable.

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.
