Description Huzaifa S. Sidhpurwala 2013-10-28 04:44:38 UTC
Security researcher Nils used the Address Sanitizer tool while fuzzing to discover a memory corruption issue with the JavaScript engine when using workers with direct proxies. This results in a potentially exploitable crash.

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