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

Description The issue is related to access to an uninitialized pointer in the WavPack audio codec. It allows a remote attacker to cause a denial of service via a DFF file lacking valid sample-rate data. The WavpackSetConfiguration64 function in pack utils.c in libwavpack.a has a condition where a conditional jump or move depends on an uninitialized value, potentially leading to an application crash.

Recommendations For versions through 5.1.0, consider disabling the WavpackSetConfiguration64 function as a temporary workaround until a patch is available. Restrict access to DFF files that lack valid sample-rate data to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
