Description:
A vulnerability has been reported in Apple iTunes, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an integer overflow error within the parsing of AAC media files (e.g. ".M4A" and ".M4P" file extensions). This can be exploited to cause a memory corruption when a malicious AAC file with a specially crafted "sample_size_table" value is opened.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been reported in versions prior to 6.0.5.
