Description Dhananjay Arunesh 2019-04-30 08:45:30 UTC

WavpackSetConfiguration64 in pack_utils.c in libwavpack.a in WavPack through
5.1.0 has a "Conditional jump or move depends on uninitialised value" condition,
which might allow attackers to cause a denial of service (application crash) via
a DFF file that lacks valid sample-rate data.

Comment 9 Marco Benatto 2019-05-07 14:12:44 UTC

When reading dsdiff format header WavPack expects the file to has sample rate information,
if sanple rate property is missing in the file to be compressed dsdiff parser doesn't initialize it with any value.
The uninitialized variable is used further when configuring the encoding engine which may lead to unexpected behavior.
