TITLE

Apple iOS and Apple TV of AppleFileConduit of afc Vulnerable to directory traversal

DESCRIPTION

Directory traversal vulnerability in afc in AppleFileConduit in Apple iOS before 8.1.3 and Apple TV before 7.0.3 allows attackers to access unintended filesystem locations by creating a symlink. Multiple Apple products are prone to multiple security vulnerabilities. The update addresses new vulnerabilities that affect AppleFileConduit, Kernel, and WebKit components. Attackers can exploit these issues to bypass security restrictions, disclose information, and perform other attacks. Apple iOS is an operating system developed for mobile devices; Apple TV is a high-definition TV set-top box product. AppleFileConduit is a component for viewing system files in jailbroken iOS devices. An attacker could exploit this vulnerability with a malicious 'afc' command to gain access to a protected file system. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 APPLE-SA-2015-01-27-2 iOS 8.1.3 iOS 8.1.3 is now available and addresses the following: AppleFileConduit Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later Impact: A maliciously crafted afc command may allow access to protected parts of the filesystem Description: A vulnerability existed in the symbolic linking mechanism of afc.
