CVE-2024-44160: 
macOS vulnerability analysis and mitigation

A buffer overflow vulnerability (CVE-2024-44160) was discovered in Apple's macOS systems, specifically affecting the Intel Graphics Driver component. The vulnerability was disclosed on September 16, 2024, and affects multiple versions of macOS including Ventura 13.7, Sonoma 14.7, and Sequoia 15. The issue involves improper memory handling when processing maliciously crafted textures (Apple Support, NVD).

The vulnerability is classified as a buffer overflow issue that occurs within the processing of MOV files in the VTDecoderXPCService process. The specific flaw stems from inadequate validation of user-supplied data, which can result in a write operation beyond the bounds of an allocated buffer. The vulnerability has received a CVSS v3.1 base score of 5.5 (MEDIUM) from NIST with vector CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, while CISA-ADP assessed it at 7.8 (HIGH) with vector CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (ZDI, NVD).

When exploited, this vulnerability can lead to unexpected application termination and potentially allow remote attackers to execute arbitrary code on affected installations of Apple macOS. The execution would occur in the context of the current user, requiring user interaction such as visiting a malicious page or opening a malicious file (ZDI).

Apple has addressed this vulnerability by implementing improved memory handling in the affected systems. The fix has been included in macOS Ventura 13.7, macOS Sonoma 14.7, and macOS Sequoia 15. Users are advised to update their systems to these versions to mitigate the vulnerability (Apple Support, NVD).
