Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU63807

Risk: High

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2021-32278

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. A remote attacker can trick the victim to open specially crafted data, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Mitigation

Install updates from vendor's website.
