Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU52802

Risk: Medium

CVSSv3.1: 3.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-31439

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the processing of DSI structures in Netatalk. A remote attacker on the local network can trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install update from vendor's website.
