This security bulletin contains information about 10 vulnerabilities.

1) Heap-based buffer overwrite

EUVDB-ID: #VU12398

Risk: Medium

CVSSv4.0: 4.5 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2018-10536

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The weakness exists in the WAV parser component due to improper rejection of multiple format chunks by the ParseRiffHeaderConfig function, as defined in the riff.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.

Mitigation

Update the affected package wavpack.
