tomcat: Client certificate verification bypass due to virtual host mapping

A certificate validation flaw has been found in Apache Tomcat. omcat did not validate that the host name provided via the SNI extension was the same as the host name provided in the HTTP host header field. If Tomcat was configured with more than one virtual host and the TLS configuration for one ...

CVE-2026-44452: Out-of-bounds Read

h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. Prior to commit 8dc37cb, when h2o receives a ClientHello message over TLS or QUIC and it contains a zero-length SNI extension, the h2o server runs over the zero-length hostname while trying to copy the hostname, assuming that it ...

curl: CVE-2024-2466: TLS certificate check bypass with mbedTLS

The Curl library had a security vulnerability where the certificate name check was bypassed when connecting to a host via its IP address. This could have potentially introduced spoofing attacks or unauthorized access due to unverified server certificate. The issue affected Curl with MbedTLS from...

Transparent Man-in-the-Middle TLS Proxy: ratched

ratched is a Man-in-the-Middle MitM proxy that specifically intercepts TLS connections. It is intended to be used in conjunction with the Linux iptables REDIRECT target; all connections that should be intercepted can be redirected to the local ratched port. Through the SOORIGINALDST sockopt,...

CVE-2015-5291

CVE-2015-5291 and CVE-2015-8036 describe heap-based buffer overflows in PolarSSL (mbed TLS) that affect PolarSSL 1.x before 1.2.17 and mbed TLS 1.3.x before 1.3.14 and 2.x before 2.1.2. The flaw stems from improper boundary handling of the hostname/SNI extension in ClientHello, enabling remote at...

mbedtls: arbitrary code execution

When the client creates its ClientHello message, due to insufficient bounds checking it can overflow the heap-based buffer containing the message while writing some extensions. Two extensions in particular could be used by a remote attacker to trigger the overflow: the session ticket extension an...

Google to Disable Weak SSLv3 and RC4 Protocols to Boost Internet Security

It is finally time to say GoodBye to the old and insecure Web security protocols. Citing the long history of weaknesses in the Secure Sockets Layer SSL 3.0 cryptographic protocol and the RC4 Cipher Suite, Google plans to disable support for both SSLv3 as well as RC4 stream cipher in its front-end...
