1) Buffer overflow

EUVDB-ID: #VU68896

Risk: Medium

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-3786

CWE-ID: CWE-119 - Memory corruption

Exploit availability: Yes

Description

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

The vulnerability exists due to a boundary error when processing the email address field length inside a X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a buffer overflow and crash the application.

Mitigation

Update the affected package openssl-3 to the latest version.

2) Improper locking

EUVDB-ID: #VU70142

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3996

CWE-ID: CWE-667 - Improper Locking

Exploit availability: No

Description

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

The vulnerability exists due to double-locking error if an X.509 certificate contains a malformed policy constraint and policy processing is enabled. A remote attacker can under certain circumstances perform a denial of service attack against the web server.

Successful exploitation of the vulnerability requires that policy processing being enabled on the server.

Mitigation

Update the affected package openssl-3 to the latest version.
