DESCRIPTION:
A weakness has been reported in Mozilla Firefox and Thunderbird,
which can be exploited by malicious people to compromise a user's
system.

A malicious JAR file could be downloaded and executed if a user is
convinced into holding down the "Enter" key via e.g. a malicious
game.

This is caused due to an incomplete fix for vulnerability #3 in:
SA46171

NOTE: This only affects the Mac OS X versions.

SOLUTION:
Update to Firefox version 3.6.25 or Thunderbird 3.1.17.
