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 Deserialize function in AudioCodecs. Crafted data in a LOAS file can trigger a read past the end of an allocated data structure. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
