Mozilla Foundation Security Advisory 2007-40

Title: Upgraded Thunderbird 1.5.0.13 missing fix for MFSA 2007-23
Impact: Critical
Announced: December 19, 2007
Reporter: Stephen Donner
Products: Thunderbird 1.5.0.13

Fixed in: Thunderbird 1.5.0.14

Description

Mozilla tester Stephen Donner reported that only users who installed Thunderbird 1.5.0.13 using the install package received the fix for MFSA 2007-23. Users who upgraded to Thunderbird 1.5.0.13 from an earlier version using the automatic update mechanism were not protected. If those users browsed the internet using Internet Explorer or another similarly affected program and clicked on a malicious mailto: link the attacker could potentially execute arbitrary code.

Workaround

Mozilla highly recommends using Firefox to browse the web to prevent attackers from exploiting this problem in Internet Explorer.
