CVE-2021-44269

Name of the Vulnerable Software and Affected Versions Wavpack version 5.4.0

Description An out of bounds read issue was discovered in the processing of *.WAV files. This issue is triggered in the WavpackPackSamples function of the file src/pack utils.c, where the tainted variable cnt is too large, causing the pointer sptr to read beyond the heap bound.

Recommendations For Wavpack version 5.4.0, consider restricting the use of the WavpackPackSamples function until a patch is available. As a temporary workaround, ensure that the cnt variable is properly validated to prevent it from exceeding the expected bounds, thus preventing the out of bounds read. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
