Heap-based buffer overwrite in WavPack - CVE-2018-10537

Vulnerability identifier: #VU12399

CSH Severity: Medium

CVSS v4: 7.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2018-10537

CWE-ID: CWE-787

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a local attacker to cause DoS condition or execute arbitrary code on the target system.

The weakness exists in the W64 parser component due to improper rejection of multiple format chunks by the ParseWave64HeaderConfig function, as defined in the wave64.c source code file. A local attacker can execute a specially crafted .wav file, trigger heap buffer overwrite and cause the service to crash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.
