Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU88211

Risk: Medium

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

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-1_1 to the latest version.
