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 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. + + ([CVE-2024-2511]) + + *Matt Caswell* + * New atexit configuration switch, which controls whether the OPENSSL_cleanup is registered when libcrypto is unloaded. This can be used on platforms where using atexit() from shared libraries causes crashes on exit. @@ -19832,6 +19850,7 @@ ndif <!-- Links --> +[CVE-2024-2511]: https://www.openssl.org/news/vulnerabilities.html#CVE-2024-2511 [CVE-2024-0727]: https://www.openssl.org/news/vulnerabilities.html#CVE-2024-0727 [CVE-2023-6237]: https://www.openssl.org/news/vulnerabilities.html#CVE-2023-6237 [CVE-2023-6129]: https://www.openssl.org/news/vulnerabilities.html#CVE-2023-6129 @@ -20,7 +20,8 @@ OpenSSL 3.0 ### Major changes between OpenSSL 3.0.13 and OpenSSL 3.0.14 [under development] - * none + * Fixed unbounded memory growth with session handling in TLSv1.3 + ([CVE-2024-2511]) ### Major changes between OpenSSL 3.0.12 and OpenSSL 3.0.13 [30 Jan 2024] @@ -1474,6 +1475,7 @@ OpenSSL 0.9.x <!-- Links --> +[CVE-2024-2511]: https://www.openssl.org/news/vulnerabilities.html#CVE-2024-2511 [CVE-2024-0727]: https://www.openssl.org/news/vulnerabilities.html#CVE-2024-0727 [CVE-2023-6237]: https://www.openssl.org/news/vulnerabilities.html#CVE-2023-6237 [CVE-2023-6129]: https://www.openssl.org/news/vulnerabilities.html#CVE-2023-6129 |
