Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU88211

Risk: Medium

CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-2511

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 unbounded memory growth when processing TLSv1.3 sessions. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that the non-default SSL_OP_NO_TICKET option is being used in TLSv1.3.

Mitigation

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