The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2020:1581 advisory.
The function WavpackPackInit in pack_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (resource exhaustion caused by an infinite loop) via a crafted wav audio file because WavpackSetConfiguration64 mishandles a sample rate of zero. (CVE-2018-19840)
The function WavpackVerifySingleBlock in open_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (out-of-bounds read and application crash) via a crafted WavPack Lossless Audio file, as demonstrated by wvunpack. (CVE-2018-19841)
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. (CVE-2019-11498)
WavPack 5.1 and earlier is affected by: CWE 369: Divide by Zero. The impact is: Divide by zero can lead to sudden crash of a software/service that tries to parse a .wav file. The component is:
ParseDsdiffHeaderConfig (dsdiff.c:282). The attack vector is: Maliciously crafted .wav file. The fixed version is: After commit https://github.com/dbry/WavPack/commit/4c0faba32fddbd0745cbfaf1e1aeb3da5d35b9fc.
(CVE-2019-1010315)
WavPack 5.1.0 and earlier is affected by: CWE-457: Use of Uninitialized Variable. The impact is:
Unexpected control flow, crashes, and segfaults. The component is: ParseCaffHeaderConfig (caff.c:486). The attack vector is: Maliciously crafted .wav file. The fixed version is: After commit https://github.com/dbry/WavPack/commit/f68a9555b548306c5b1ee45199ccdc4a16a6101b. (CVE-2019-1010317)
WavPack 5.1.0 and earlier is affected by: CWE-457: Use of Uninitialized Variable. The impact is:
Unexpected control flow, crashes, and segfaults. The component is: ParseWave64HeaderConfig (wave64.c:211).
The attack vector is: Maliciously crafted .wav file. The fixed version is: After commit https://github.com/dbry/WavPack/commit/33a0025d1d63ccd05d9dbaa6923d52b1446a62fe. (CVE-2019-1010319)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
