CVE-2024-44284: 
macOS vulnerability analysis and mitigation

An out-of-bounds write vulnerability (CVE-2024-44284) was discovered in Apple macOS's ICC profile parsing functionality. The vulnerability affects macOS Ventura and Sonoma versions, and was fixed in macOS Ventura 13.7.1 and macOS Sonoma 14.7.1, released on October 28, 2024. The vulnerability was discovered by researchers Junsung Lee and dw0r! working with Trend Micro Zero Day Initiative (Apple Support, ZDI Advisory).

The vulnerability exists within the parsing of ICC profiles in macOS. The specific flaw results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (High) with the vector string AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating local access with user interaction required (ZDI Advisory).

If successfully exploited, this vulnerability allows attackers to execute arbitrary code in the context of the current process. The exploitation can lead to unexpected application termination and potential code execution when parsing maliciously crafted files (Apple Support, ZDI Advisory).

Apple has released security updates to address this vulnerability in macOS Ventura 13.7.1 and macOS Sonoma 14.7.1. Users are advised to update their systems to these versions to protect against potential exploitation (Apple Support, Apple Support).
