Description
An issue was discovered in WavPack 5.1.0 and earlier for DSDiff input. Out-of-bounds writes can occur because ParseDsdiffHeaderConfig in dsdiff.c does not validate the sizes of unknown chunks before attempting memory allocation, related to a lack of integer-overflow protection within a bytes_to_copy calculation and subsequent malloc call, leading to insufficient memory allocation.
