Apple rolled out a late day security update on Thursday that addressed potential DNS-related flaws in Mac OS X Leopard and Tiger. Security Update 2008-005 prevents malicious attackers from forging Web sites -- a trick that could potentially be used for phishing attacks where hackers trick Web surfers into giving up personal information like passwords and bank account data.

The security update fixed flaws that could allow an attacker to use the Open Scripting Architecture to run commands with elevated privileges. It also addressed problems where maliciously crafted Web sites could use CoreGraphics to crash applications or run arbitrary code, maliciously crafted messages could use Data Detectors to crash applications, emac could be used to gain System Privileges after Disk Utilityis Repair Permissions tool has been run, and OpenLDAP and OpenSSL could be used to crash applications or run arbitrary code.

PHP was updated to version 5.2.6 to block several potential security issued that could lead to crashed applications or arbitrary code execution.

A flaw in QuickLook was patched that could lead to crashed apps or arbitrary code execution, and rsync was updated to prevent remote attackers from accessing or overwriting the module root.

Security Update 2008-005 requires Mac OS X 10.4.11 or 10.5.4, or Mac OS X Server 10.4.11 or 10.5.4. It is available via Appleis Software Update application, or as a downloadable installer at the Apple Support Web site.
