1) Resource exhaustion

EUVDB-ID: #VU73960

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-0464

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when verifying X.509 certificate chains that include policy constraints. A remote attacker can create a specially crafted certificate to trigger resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.
