Out-of-Bounds Write Vulnerability in WavPack DSDiff Input

CVE-2018-10539 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:N/A:P

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.
