TITLE

Apple iOS of ImageIO Memory double free vulnerability

DESCRIPTION

Double free vulnerability in ImageIO in Apple iOS before 6 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted JPEG image. Apple iOS for the iPhone, the iPod touch, and the iPad is prone to remote code-execution vulnerability. Successfully exploiting this issue will allow the attacker to execute arbitrary code in the context of the affected application. Failed exploit attempts may result in a denial-of-service condition. Note: This issue was previously discussed in BID 55612 (Apple iPhone/iPad/iPod touch Prior to iOS 6 Multiple Vulnerabilities) but has been given its own record to better document it. Apple iOS is an operating system developed by Apple (Apple) for mobile devices. A double free vulnerability exists in ImageIO in versions prior to Apple iOS 6. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 APPLE-SA-2012-09-24-1 Apple TV 5.1 Apple TV 5.1 is now available and addresses the following: Apple TV Available for: Apple TV 2nd generation and later Impact: Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution Description: An uninitialized memory access existed in the handling of Sorenson encoded movie files.
