CVE-2026-94419 Client session cache reference poisoning allows resumption with wrong server

Without NOSESSIONCACHEREF, wolfSSLgetsession does not return a session object but a ClientSession reference of the form row, index, hashsessionID into the process-global SessionCache, and ClientSessionToSession validates it against that hash alone. Because the TLS 1.2 session ID is chosen by the...

Name of the Vulnerable Software and Affected Versions Apache Tomcat Native versions 1.3.0 through 1.3.8 Apache Tomcat Native versions 2.0.0 through 2.0.15 Description Apache Tomcat Native enables several insecure OpenSSL options by default. These include ALLOW CLIENT RENEGOTIATION, NO EXTENDED...

Astra Linux – Vulnerability in openssl1.0

The Raccoon attack exploits a flaw in the TLS specification, which allows an attacker to calculate the pre-master secret in connections that use a Diffie-Hellman DH-based ciphersuite. In such cases, the attacker can eavesdrop on all encrypted communications sent over that TLS connection. The atta...

JLSEC-2026-802 TLS 1.2 session resumption can renew one master secret indefinitely

Reseau 1.1.0 through 1.3.1 issue a fresh TLS 1.2 session ticket after a resumed handshake by copying the original master secret while resetting the ticket's creation and expiry times. A client that resumes at least once during every ticket lifetime can keep the same master secret valid...

JLSEC-2026-231 openssl-src subject to Timing Oracle in RSA Decryption

A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages fo...

CVE-2021-22981

On all versions of BIG-IP 12.1.x and 11.6.x, the original TLS protocol includes a weakness in the master secret negotiation that is mitigated by the Extended Master Secret EMS extension defined in RFC 7627. TLS connections that do not use EMS are vulnerable to man-in-the-middle attacks during...

F5 Networks BIG-IP : TLS Triple Handshake Attack vulnerability (K000132686)

The version of F5 Networks BIG-IP installed on the remote host is prior to 17.1.0.1. It is, therefore, affected by a vulnerability as referenced in the K000132686 advisory. The original TLS protocol includes a weakness in master secret negotiation, potentially allowing the Triple Handshake Attack...

CVE-2024-24272

An issue in iTop DualSafe Password Manager & Digital Vault before 1.4.24 allows a local attacker to obtain sensitive information via leaked credentials as plaintext in a log file that can be accessed by the local user without knowledge of the master secret...

CVE-2023-3724
