McAfee Offers Protection Against New Mac OS X Exploits

The Apple Mac OS X Command Execution Vulnerability (February 24, 2006)

McAfee, Inc. (NYSE: MFE), the leading dedicated security technology company, today announced that it provides protection from attacks targeting the newly discovered Apple Mac OS X Command Execution Vulnerability and the recent worms targeting the Mac OS X platform, including OSX/Inqtana.a and OSX/Leap. While McAfee(R) AVERT(R) Labs, the world-class research division of McAfee, Inc., has traditionally viewed Mac threats as a non-issue and rates the worms Low-Profile at this time, it does believe these threats demonstrate a renewed interest by the malware authoring community in the Mac OS platform.

The Apple Mac OS X Command Execution Vulnerability, which was discovered February 21 by Michael Lehn, is a critical vulnerability that exists when accessing specially crafted files. Both proof of concept exploits and malicious exploit code are public, and a patch is not yet available. Apple Mail and Safari have been identified as attack vectors for this vulnerability.

OSX/Inqtana.a, which was discovered February 18, is a proof of concept worm that exploits an Apple Mac OS X Directory traversal vulnerability in the Bluetooth file and object exchange services (CVE-2005-1333). This worm spreads over the Bluetooth OBEX Push service, which typically requests the user to accept a file transfer over Bluetooth. It also exploits a directory traversal vulnerability in Mac OS X to install and auto-start the worm on the infected machine. Users are advised not to accept requests from unknown devices.

OSX/Leap, which was discovered February 16, is an instant messaging worm propagating via iChat on PowerPC-based machines running Mac OS X. The worm sends itself to people on the user's buddy list in the form of a .tgz archive and attempts to masquerade as a jpeg image file to trick the user into executing it. OSX/Leap requires user interaction in order to infect a machine.

McAfee Solutions

McAfee Virex(R) for Macintosh(R) offers protection against OSX/Inqtana.a and OSX/Leap, and the known exploits targeting the unpatched Command Execution vulnerability. McAfee Virex, designed for the Mac OS X operating system provides real-time prevention of viruses, worms, Trojans and other potentially unwanted programs across their Macintosh and heterogeneous environments.
