Gentoo update for WavPack

1) Infinite loop

EUVDB-ID: #VU16283

Risk: Low

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2018-19840

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists in the WavpackPackInit function, as defined in the pack_utils.csource code file due to the WavpackSetConfiguration64 function improperly handles a block sample rate of zero. A remote attacker can trick the victim into accessing a .wav file that submits malicious, trigger an infinite loop condition that could consume excessive resources and cause the affected software to crash, resulting in a DoS condition.

Mitigation

Update the affected packages.
media-sound/wavpack to version: 5.3.2

Vulnerable software versions

Gentoo Linux: All versions

2) Out-of-bounds read

EUVDB-ID: #VU16282

Risk: Low

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2018-19841

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists in the WavpackVerifySingleBlock function, as defined in the open_utils.c source code file due to improper processing of WavPack lossless audio files. A remote attacker can trick the victim into accessing a WavPack lossless audio file that submits malicious, trigger an out-of-bounds read condition and cause the affected software to crash, resulting in a DoS condition.

Mitigation

Update the affected packages.

3) Input validation error

EUVDB-ID: #VU19226

Risk: Low

CVSSv3.1: 5.4 [CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H/E:P/RL:U/RC:C]

CVE-ID: CVE-2019-11498

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the WavpackSetConfiguration64() function in the pack_utils.c file within the libwavpack.a. A remote attacker can trick the victim to open a specially crafted DFF file that lacks valid sample-rate data and crash the affected application. 

Mitigation

Update the affected packages.
media-sound/wavpack to version: 5.3.2
