CVE-2025-24123

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 parsing of MOV files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

macOS Sequoia 15.3 addresses buffer overflow, bypass, code execution, information leakage, integer overflow, null pointer, out of bounds read, out of bounds write, spoofing, and use-after-free vulnerabilities.
