Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU12888

Risk: Low

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-6888

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the "read_metadata_vorbiscomment_()" function in src/libFLAC/stream_decoder.c due to memory leak. A remote attacker can trick the victim into opening a specially crafted FLAC file and cause the service to crash.

Mitigation

Install update from vendor's website.
