Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU16283

Risk: Low

CVSSv4.0: 5.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

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

Install updates from vendor's website.

2) Out-of-bounds read

EUVDB-ID: #VU16282

Risk: Low

CVSSv4.0: 5.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

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

Install updates from vendor's website.

3) Input validation error

EUVDB-ID: #VU19226

Risk: Low

CVSSv4.0: 3.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

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

Install updates from vendor's website.

EUVDB-ID: #VU19216

Risk: Low

CVSSv4.0: 5.2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2019-1010315

CWE-ID: CWE-369 - Divide By Zero

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause a denial of service (DoS) condition on a targeted system.

The vulnerability exists due to a divide by zero error in the "ParseDsdiffHeaderConfig()" function in the "dsdiff.c" file, when parsing .wav files.

A remote attacker can trick a victim to open a specially crafted .wav file and crash the affected application.

Mitigation

CVE-ID: CVE-2019-1010317

CWE-ID: CWE-665 - Improper Initialization

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause a denial of service (DoS) condition on a targeted system.

The vulnerability exists due to an uninitialized read condition in the "ParseCaffHeaderConfig()" function in the caff.c file when parsing .wav files. A remote attacker can persuade a user to access a .wav file that submits malicious input to the targeted system and perform a DoS attack.
