Description

Mozilla team members discovered several crashes during testing of the browser engine showing evidence of memory corruption that we presume is exploitable.

Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail.

Workaround

Disable Javascript until you can upgrade to a fixed version.
