This vulnerability allows remote attackers to disclose sensitive information on affected installations of Apple macOS. 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 the processing of MOV files in the VTDecoderXPCService process. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.
