Who is Vulnerable?
Vulnerability Description Apple iTunes is a multimedia player that supports a wide range of media formats. The software supports parsing and displaying picture files as well as numerous video and audio formats. One of the formats that the player is capable of processing is the protected advanced audio coding (AAC) media file format. An integer overflow vulnerability exists in Apple iTunes. The vulnerability is caused due to an improper handling the sample table size atom (STSZ) when processing AAC media files. An attacker may exploit the vulnerability by delivering a crafted AAC media file to a target user and enticing the user to open it, resulting in execution of arbitrary code on the target host within the security context of the current user. In case of an attack where code injection and execution is successful, the behavior of the target system is entirely dependent on the intended purpose of the injected code. Any code executed by the attacker will run with the privileges of the currently logged in user. In case of an attack where code injection is not successful, the process will terminate abnormally.
