Security Update - ShellBlock
ShellBlock is a security fix update for Bug 250180. It disables the ability to call the shell protocol from within affected Mozilla programs.

This update is for users of Mozilla 1.x (up to Mozilla 1.7), Mozilla Firefox (up to 0.9.1), and Mozilla Thunderbird (up to 0.7.1) on Microsoft Windows 2000 and XP only.
Mozilla 1.7.1, Firefox 0.9.2 and Thunderbird 0.7.2 have been released with this fix included.
