Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Stack-based buffer overflow

EUVDB-ID: #VU56239

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-3622

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error when processing hive child objects. A local user can create a specially crafted Windows Registry (hive) file which would cause hivex to recursively call the _get_children() function, ultimately leading to a stack overflow and library crash.

Mitigation

Install updates from vendor's repository.
