Technical details
An out-of-bounds access vulnerability (encompassing both CWE-125: Out-of-bounds Read and CWE-787: Out-of-bounds Write) exists across multiple Apple operating systems. The issue is rooted in insufficient bounds checking during the processing of media files. An attacker can exploit this by tricking a user into opening a maliciously crafted media file (User Interaction required). Successful exploitation can lead to unexpected application termination or process memory corruption. Apple has addressed this issue by improving bounds checking in the latest updates for iOS, iPadOS, macOS, tvOS, visionOS, and watchOS.
