DESCRIPTION:
A security issue has been reported in Apple Mac OS X, which can be
exploited by malicious people with physical access to bypass certain
security restrictions.

The security issue is caused due to the debug switch being enabled
within FileVault when using "Legacy FileVault". This may lead to
users' password being saved in DEBUGLOG in plain text and can be
exploited to read the password via FireWire target disk mode.

Successful exploitation requires that OS X is upgraded from an older
version and uses the "Legacy FileVault" feature.

The security issue is reported in version 10.7.3.

SOLUTION:
As a workaround use FileVault 2.
