Application crash via zero-bit coordinate shift
Published Jul 19, 2022 · Updated Aug 3, 2024
Integer overflow in GPAC before 2.1-DEV allows context-dependent attackers to crash MP4Box through a crafted LASeR scene file. The lsr_translate_coords function subtracts one from a zero-bit coordinate width and uses the wrapped result as a shift exponent. A user must direct MP4Box to parse the file; the demonstrated outcomes are a process crash or an unexpected coordinate value, not code execution.
