CVE-2018-10539: An issue was discovered in WavPack 5.1.0 and earlier for DSDiff input.

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.

Security readout for executives and security teams

Plain-English summary

CVE-2018-10539 is a memory-safety flaw in WavPack 5.1.0 and earlier when handling DSDiff audio input. A malformed audio file can trigger out-of-bounds writes. Public sources show vendor and Linux distribution updates, but the bundle does not show known active exploitation.

Executive priority

Treat as a patching item for endpoints or services that process untrusted audio. It is not KEV-listed in the supplied bundle, so prioritize by exposure rather than emergency response.

Technical view

In dsdiff.c, ParseDsdiffHeaderConfig does not validate unknown chunk sizes before allocation. Missing integer-overflow protection in a bytes_to_copy calculation can cause malloc to allocate too little memory, followed by out-of-bounds writes while processing DSDiff input.

Likely exposure

Exposure is most likely where WavPack 5.1.0 or earlier is installed and processes untrusted or user-supplied DSDiff audio. Linux systems using distro packages should check Debian, Ubuntu, Slackware, and Fedora advisory coverage for their release.

Exploitation context

The source bundle does not include CVSS, CWE mapping, proof of active exploitation, or CISA KEV listing. The practical trigger appears to require processing a malformed DSDiff file with vulnerable WavPack code.

Researcher notes

The core issue is integer-overflow-driven under-allocation followed by out-of-bounds writes in DSDiff chunk handling. Evidence identifies the vulnerable function and upstream fix, but the supplied record lacks CVSS, exploit maturity, and affected CPE detail.

Mitigation direction

  • Upgrade WavPack packages using vendor or distribution security advisories.
  • Prioritize systems that process untrusted audio files automatically.
  • Check upstream WavPack commit and release guidance for the corrected parsing behavior.
  • Limit ingestion of untrusted DSDiff audio until patched.
  • Use distro-supported packages where Debian, Ubuntu, Slackware, or Fedora updates apply.

Validation and detection

  • Inventory installed WavPack versions and flag 5.1.0 or earlier.
  • Confirm distro package versions include the referenced security update.
  • Review applications or pipelines that invoke WavPack on user-supplied audio.
  • Test patched systems with normal DSDiff processing to confirm compatibility.
  • Document any remaining unpatched hosts and compensating controls.
