WavPack ParseWave64HeaderConfig() Denial of Service Vulnerability [CVE-2019-1010319]

CVE Number – CVE-2019-1010319

A vulnerability in WavPack could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted system.

The vulnerability is due to an uninitialized read condition that could occur in the ParseWave64HeaderConfig() function, as defined in the wave64.c source code file of the affected software, when parsing .wav files. An attacker could exploit this vulnerability by persuading a user to access a .wav file that submits malicious input to the targeted system. A successful exploit could result in a DoS condition. 

Proof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available. 

WavPack has confirmed the vulnerability and released software updates.

Analysis

• To exploit this vulnerability, an attacker may use misleading language or instructions to persuade a user to access a .wav file that submits malicious input to the targeted system.
