概要
CVE-2024-2511 is narrow: OpenSSL itself rates it low severity because it depends on specific non-default TLS server behavior. For teams shipping their own TLS gateways or reverse-proxy images, the useful signal is not an OpenSSL version alone; it is a vulnerable release line paired with configuration that can put TLSv1.3 session handling on the affected path.
仕組み
The repo check looks for explicit OpenSSL version evidence in build metadata, then requires TLSv1.3 server configuration evidence showing session-ticket or no-ticket behavior associated with the advisory. The finding stays scoped to source/config evidence and does not claim FixVibe observed memory growth on the live service.
被害範囲
If the affected OpenSSL runtime is the one terminating TLS and the non-default session configuration is active without the advisory exception, repeated TLSv1.3 session activity can cause unbounded memory growth and denial of service. A repo match should trigger runtime-version and deployment review before anyone treats it as confirmed production exposure.

What FixVibe checks
FixVibe repo scans look for high-confidence security patterns and dependency risk in source context. Reports identify the affected area and recommended fix. For check-specific questions about exact detection heuristics, active payload details, or source-code rule patterns, contact support@fixvibe.app.
鉄壁の防御
Upgrade the OpenSSL runtime that terminates TLS to 3.2.2, 3.1.6, 3.0.14, 1.1.1y, or a vendor-patched equivalent, then rebuild and redeploy the TLS-serving binary or image. Review whether session tickets must be disabled; if they must, keep the setting only with a patched runtime and document any early_data anti-replay exception.
