Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU88211
Risk: Medium
CVSSv4.0: 4.6 [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
DescriptionThe 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.
