In this article “Apple’s latest update to OS X contains a dangerous programming error that reveals the passwords for material stored in the first version of FileVault, the company’s encryption technology, a software consultant said.
David I. Emery wrote on Cryptome that a debugging switch inadvertently left on in the current release of Lion, version 10.7.3, records in clear text the password needed to open the folder encrypted by the older version of FileVault.
Users who are vulnerable are those who upgraded to Lion but are using the older version of FileVault. The debug switch will record the Lion passwords for anyone who has logged in since the upgrade to version 10.7.3, released in early February.”
