Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

UPDATED: 17.07.2019

Added vulnerabilities #2-4.

1) 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

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

2) Improper Initialization

EUVDB-ID: #VU19217

Risk: Low

CVSSv3.1: 6.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:U/RC:C]

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.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
