JLSEC-2026-673
In wolfSSL before 5.5.1, malicious clients can cause a buffer overflow during a TLS 1.3 handshake. This occurs when an attacker supposedly resumes a previous TLS session. During the resumption Client Hello a Hello Retry Request must be triggered. Both Client Hellos are required to contain a list ...
CVE-2026-1677
Zephyr sockets created with IPPROTOTLS13 can still negotiate a TLS 1.2 connection when both TLS versions are enabled in Kconfig, because the socket-level protocol selection is not propagated to mbedTLS e.g. via mbedtlssslconfmintlsversion. The ClientHello advertises both versions and the peer can...

CVE-2026-29129
A flaw was found in Apache Tomcat. This vulnerability occurs when the configured cipher preference order is not preserved. This could allow an attacker to bypass intended security configurations, potentially leading to a weakened security posture or information disclosure. Mitigation Configure...
EUVD-2026-9008
An attacker may exploit the use of weak CBC-based cipher suites in the device’s SSH service to potentially observe or manipulate parts of the encrypted SSH communication, if they are able to intercept or interact with the network traffic...

CVE-2026-1626
The vulnerability CVE-2026-1626 affects SICK LMS1000 and SICK MRS1000 devices, where the SSH service may accept weak CBC-based cipher suites. This could allow an attacker with network access to observe or manipulate portions of SSH communications. Red Hat and other sources corroborate a CBC-relat...

CVE-2026-27017
uTLS is a fork of crypto/tls, created to customize ClientHello for fingerprinting resistance while still using it for the handshake. Versions 1.6.0 through 1.8.0 contain a fingerprint mismatch with Chrome when using GREASE ECH, related to cipher suite selection. When Chrome selects the preferred...
TestSSL 3.2.3
testssl.sh is a free command line tool which checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws, and much more. It is written in pure bash, makes only use of standard Unix utilities, openssl and last but not least bash sockets...
OpenSSL security vulnerabilities
OpenSSL is an open-source encryption library developed by the OpenSSL team that enables the implementation of Secure Sockets Layer SSLv2/v3 and Secure Transport Layer TLSv1 protocols. This product supports various encryption algorithms, including symmetric ciphers, hash algorithms, and secure has...

Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: gnutls (UTSA-2025-990960)
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-990960 advisory. A NULL pointer dereference flaw was found in the GnuTLS software in gnutlsfigurecommonciphersuite. Tenable has extracted the preceding description block directly fro...
curl: Incorrect sizeof() in Rustls Backend Memory Allocation
Summary There's a bug in lib/vtls/rustls.c where malloc uses sizeofciphersuites instead of sizeofciphersuites. This allocates memory based on pointer size rather than element size. Steps To Reproduce 1. Look at lib/vtls/rustls.c line 530: c const struct rustlssupportedciphersuite ciphersuites =...
