Out-of-bounds read in libsndfile - CVE-2017-6892

Vulnerability identifier: #VU10816

CSH Severity: Low

CVSS v4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2017-6892

CWE-ID: CWE-125

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists in the aiff_read_chanmap() function, which is defined in the aiff.c source code file due to improper handling of AIFF files. A remote attacker can create a specially crafted AIFF file, trick the victim into opening it, trigger out-of-bounds read and gain access to potentially sensitive information.
