Apple macOS CFFromShiftJISLen Out-Of-Bounds Read Remote Code Execution

This vulnerability allows remote attackers to execute arbitrary code 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 CFFromShiftJISLen function. Crafted data in a DOC file can trigger a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
