CVE-2019-1010319

Name of the Vulnerable Software and Affected Versions WavPack versions 5.1.0 and earlier

Description The issue is related to the use of uninitialized variables in the ParseWave64HeaderConfig component of the WavPack audio codec. This can lead to unexpected control flow, crashes, and segfaults when a maliciously crafted .wav file is processed. The attack vector is a malicious .wav file.

Recommendations For WavPack versions 5.1.0 and earlier, update to a version after commit https://github.com/dbry/WavPack/commit/33a0025d1d63ccd05d9dbaa6923d52b1446a62fe to resolve the issue. As a temporary workaround, consider avoiding the use of the ParseWave64HeaderConfig function until a patch is available. Restrict access to malicious .wav files to minimize the risk of exploitation.
