Crashes with evidence of memory corruption (1.5.0.2)


As  part of the Firefox 1.5.0.2 release we fixed several crash bugs to
improve the stability of the product, with a particular focus on finding
crashes caused by DHTML. Some of these crashes showed evidence of memory
corruption that we presume could be exploited to run arbitrary code with
enough effort.

Note:  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

Upgrade to the fixed versions. Do not enable JavaScript in Thunderbird or
the mail portion of SeaMonkey.
