Title: Fixes for crashes with potential memory corruption (rv:1.8.0.4)
Impact: Critical
Date: June 1, 2006
Reporter: Mozilla Developers
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox 1.5.0.4
  Thunderbird 1.5.0.4
  SeaMonkey 1.0.2

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.
