发布于3月6日3月6日 Members Juniper Junos OS: 2024-10 Security Bulletin: Junos OS: Multiple vulnerabilities resolved in OpenSSL (JSA88107) (multiple CVEs) Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 10/09/2024 Created 10/10/2024 Added 10/10/2024 Modified 11/15/2024 Description Issue summary: Some non-default TLS server configurations can cause unbounded memory growth when processing TLSv1.3 sessions Impact summary: An attacker may exploit certain server configurations to trigger unbounded memory growth that would lead to a Denial of Service This problem can occur in TLSv1.3 if the non-default SSL_OP_NO_TICKET option is being used (but not if early_data support is also configured and the default anti-replay protection is in use). In this case, under certain conditions, the session cache can get into an incorrect state and it will fail to flush properly as it fills. The session cache will continue to grow in an unbounded manner. A malicious client could deliberately create the scenario for this failure to force a Denial of Service. It may also happen by accident in normal operation. This issue only affects TLS servers supporting TLSv1.3. It does not affect TLS clients. The FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue. OpenSSL 1.0.2 is also not affected by this issue.
