Title: Buffer overflow in crypto.signText()
Impact: Critical
Date: June 1, 2006
Reporter: Mikolaj J. Habryn
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox
  SeaMonkey 1.0.2


Mikolaj Habryn discovered an array index bug in crypto.signText() that results in overflowing an allocated array of pointers by two when optional Certificate Authority name arguments are passed in.

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.


Disable JavaScript until upgraded to the fixed version.
