Apple has released updates for its Lion operating system and Safari web browser, hoping to fix a slew of security flaws.
The 10.7.4 Lion upgrade aims to fix a number of bugs on the operating system, including resolving the data encryption problem on its FileVault software.
Without the update, Lion users' machines run a version of FileVault that automatically has its debugging option turned on. This means the application stores users' passwords as a plain text file on the machine.
F-Secure analyst Sean Sullivan said while the flaw cannot be used to take control of a user's device, it does still represent a security risk.
"Storing password information as plain text is a bit like stashing your spare house key under the doormat. Doing so doesn't guarantee your home will be burgled, but it sure does make life easy for any thief that might happen to come along," Sullivan told V3.
The update also includes a new version of the Safari web browser. Apple claims this will be more stable and has a new security feature that checks whether the device is running a version of Adobe Flash Player older than 10.1.
The feature should encourage users to upgrade to a more secure version, meaning they will be less vulnerable to cyber criminals.
Flash and Java have become a key area targeted by hackers in recent months, with a number of trojans and botnets being discovered targeting exploits in the programs.
Other key improvements include patches for minor flaws in other Apple applications, such as QuickTime, and coding software like Samba, Ruby and PHP.
