This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime Player. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within how the application parses a header containing codec-specific data. When handling an error case, the application will forget to initialize a pointer which will later be used in a memory operation. This can lead to code execution under the context of the application.
