Apple fixes FileVault bug in latest Lion OS update

On Wednesday, Apple issued the latest update to their Lion operating system, with the roll-out of  OS X 10.7.4. The update brought with it a fix to Apple’s recently discovered FileVault bug, in addition to introducing some improvements, reports PCMag. The bug, which was discovered earlier this month, pertained to Apple's legacy encryption software, FileVault. The flaw arose out of a debugging option left turned on by accident and led to the previous version (10.7.3) to store encrypted passwords in plain text in a log file. What this did was that it allowed anyone with some tech skills and admin access to a person's computer, to open the file containing the personal data and access the encrypted data. Reportedly, the bug only affected those running v10.7.3 and using legacy FileVault (from v.10.6).

A report by ZDNet, reveals this report stated that the FileVault bug was first pointed out in February by a user in Apple’s support forums. This happened close on the heels of the release of v.10.7.3 of the OS. The user, however, wasn't responded to. It adds, "Then last Friday, a security researcher emailed Cryptome readers, thoroughly describing the issue, which immediately led to a media maelstrom. Following its usual stance of not disclosing, discussing, or confirming security issues until patches are available, Apple did not respond publicly."
