Descriptions
An integer overflow was addressed with improved input validation. This issue is fixed in iOS 16.7.9 and iPadOS 16.7.9, macOS Ventura 13.6.8, iOS 17.6 and iPadOS 17.6, watchOS 10.6, tvOS 17.6, visionOS 1.3, macOS Sonoma 14.6. Processing a maliciously crafted file may lead to unexpected app termination.
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 parsing of KTX files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current user.
macOS Sonoma 14.6 addresses buffer overflow, bypass, code execution, information leakage, integer overflow, out of bounds access, out of bounds read, out of bounds write, spoofing, and use-after-free vulnerabilities.
