Descriptions

Se abordó un problema de corrupción de memoria con una comprobación mejorada. Este problema es corregido en tvOS versión 15.4, iOS versión 15.4 y iPadOS versión 15.4, watchOS versión 8.5. El procesamiento de una imagen diseñada de forma maliciosa puede conllevar a una corrupción de la pila

AppleVideoDecoder suffers from an out-of-bounds free vulnerability. The attached video file contains a malformed HEVC Decoder Configuration Record that leads to an out-of-bounds free in CreateHeaderBuffer. When copying the VPS, PPS and SPS, the destination pointer is incremented, and if the copied data is larger than the length specified in the input file, it breaks and falls through to a condition that frees the destination pointer, even though it has been incremented. This could free the chunk allocated next to the destination memory.
