CVE-2024-2511

A flaw was found in OpenSSL. A malicious client can trigger an uncontrolled memory consumption, resulting in a Denial of Service. This issue occurs due to OpenSSL's TLSv1.3 session cache going into an incorrect state, leading to it failing to flush properly as it fills. OpenSSL must be configured with the non-default SSL_OP_NO_TICKET option enabled to be vulnerable. This issue only affects TLSv1.3 servers, while TLS clients are not affected.

The OpenSSL version shipped with Red Hat Enterprise Linux 7 is not affected by this issue, as the version 1.0.2 does not contain the related bug.
