cve-2020-13777

Zeek test script for CVE-2020-13777 This script performs a simple test to check if a server is potentially vulnerable to CVE-2020-13777. CVE-2020-13777 causes GnuTLS to create unencrypted session tickets. This seems to be detectable by checking gnutls sets the keyname to zero - for which it uses...

CVE-2026-111815

Apache Traffic Server is vulnerable to a flaw where it can resume a TLS session across different SNI virtual hosts without re-verifying a client certificate. This bypasses the verify_client STRICT policy required by the host being resumed to. Affected versions include 8.0.0 through 8.1.11 , 9.0.0...

CVE-2026-111815 Apache Traffic Server: TLS session ticket resumption bypasses per-SNI verify_client STRICT enforcement

Apache Traffic Server can resume a TLS session across SNI virtual hosts without re-verifying a client certificate required by the resumed host's verifyclient STRICT policy. This issue affects Apache Traffic Server: from 8.0.0 through 8.1.11, from 9.0.0 through 9.2.15, from 10.0.0 through 10.1.4,...

CVE-2026-97629

A flaw was found in nginx. Under specific configurations where shared SSL session caching is enabled without explicit session ticket key rotation, a remote unauthenticated attacker may be able to forge client Secure Sockets Layer SSL sessions. This flaw allows an attacker to bypass client...

FreeBSD : nginx -- multiple vulnerabilities (95970257-c867-11f1-9006-3497f65b111b)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 95970257-c867-11f1-9006-3497f65b111b advisory. The nginx developers report: A buffer overflow might occur in a worker process when using the...

Enc53: DNSSEC-Anchored Stateless Tickets for Post-Quantum Authoritative DNS

DNSSEC authenticates RRsets, but does not provide endpoint authentication or channel security. DNS-over-TLS DoT and DNS-over-QUIC DoQ can facilitate such needs, but were designed for the stub-to-resolver hop, where stable long-lived connections amortize the expensive initial setup. The...

curl: TLS session cache case-folds CA paths and bypasses the active trust profile

curl 8.21.0 case-folds the entire TLS session-cache peer key, so two distinct CA files whose Unix paths differ only by case can share a TLS session ticket. At lib/vtls/vtlsscache.c:723, curlstrequal compares keys that include case-sensitive CA, CRL, and issuer paths, even though...

Erlang/OTP 22.2 < 27.3.4.14 / 28.0 < 28.5.0.3 / 29.0 < 29.0.3 DoS (CVE-2026-55952)

The version of Erlang/OTP installed on the remote host is 22.2 prior to 27.3.4.14, 28.0 prior to 28.5.0.3, or 29.0 prior to 29.0.3. It is, therefore, affected by a vulnerability: - The Erlang/OTP ssl application does not validate that the PSK identity list and binder list carried in a TLS 1.3...
