Description
Apple QuickTime Player for Windows contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code or cause a denial of service (DoS) condition on a targeted system.

The vulnerability is due to a memory corruption error when the affected software handles movie files. An attacker could exploit this vulnerability by convincing a user to open a malicious movie file. An exploit could trigger memory corruption that allows an attacker to execute arbitrary code or cause a DoS condition on the targeted system.

Functional code that exploits this vulnerability is available as part of the Metasploit framework.

Apple has confirmed this vulnerability and released updated software.
 
Warning Indicators
Apple QuickTime for Windows versions prior to 7.7.4 are vulnerable.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a file to the user and persuade the user to open or execute the file by using misleading language or instructions.
 
Vendor Announcements
Apple has released a security advisory at the following link: HT5770
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code or cause the application to terminate unexpectedly, resulting in a DoS condition. A successful exploit could result in a complete compromise.
 
Technical Information
The vulnerability is due to improper handling of data lengths of certain atoms such as rdrf or dref in the Alis record, which could overflow the buffer and corrupt memory.

An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to open a crafted .mov file. Successful exploitation could trigger memory corruption and allow the attacker to execute arbitrary code under the context of the user.
