ciphertest

cipherTest.sh by Patrick Bogen cipherTest.sh is a "better" SSL cipher checker in that it uses gnutls, which has support for many more configurations than openssl. It tests potentially 3,200 different configurations but does some pre-optimization so that it minimizes "failed" checks. It relies on...

CVE-2026-59272

A flaw was found in the Log4j2 AMQP Appender. When configured to ship logs to RabbitMQ over Transport Layer Security TLS, the appender disables hostname verification by default. This misconfiguration allows a remote attacker to perform a man-in-the-middle MITM attack, intercepting sensitive log...

CVE-2026-8932 incomplete mTLS config matching in conn reuse

libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, some TLS...
