CVE-2024-44161: 
macOS vulnerability analysis and mitigation

CVE-2024-44161 is an out-of-bounds read vulnerability discovered in Apple macOS's Intel Graphics Driver component. The vulnerability was disclosed on September 16, 2024, and affects multiple versions of macOS including Ventura, Sonoma, and Sequoia. The issue was identified by Michael DePlante (@izobashi) of Trend Micro Zero Day Initiative (Apple Support, ZDI Advisory).

The vulnerability exists within the processing of MOV files in the VTDecoderXPCService process. The specific flaw stems from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer when processing maliciously crafted textures. The vulnerability has been assigned a CVSS v3.1 base score of 5.5 (MEDIUM) with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H (NVD, ZDI Advisory).

When exploited, this vulnerability can lead to unexpected application termination when processing maliciously crafted textures. The vulnerability could potentially allow attackers to disclose sensitive information on affected installations of Apple macOS (Apple Support, ZDI Advisory).

The vulnerability requires user interaction to exploit, specifically the target must visit a malicious page or open a malicious file. An attacker could potentially leverage this vulnerability in conjunction with other vulnerabilities to execute arbitrary code in the context of the current user (ZDI Advisory).

Apple has addressed this vulnerability by implementing improved bounds checking in the following macOS versions: macOS Ventura 13.7, macOS Sonoma 14.7, and macOS Sequoia 15. Users are advised to update their systems to these patched versions to mitigate the risk (Apple Support).
