DEBIAN-CVE-2020-24613

wolfSSL before 4.5.0 mishandles TLS 1.3 server data in the WAITCERTCR state, within SanityCheckTls13MsgReceived in tls13.c. This is an incorrect implementation of the TLS 1.3 client state machine. This allows attackers in a privileged network position to completely impersonate any TLS 1.3 servers...

Unspecified Vulnerability in Tridium Niagara and Niagara Enterprise Security

Niagara is a suite of platforms for supporting device and application connectivity. A security vulnerability exists in Tridium Niagara and Niagara Enterprise Security that stems from a timeout during the TLS handshake, where the program is unable to interrupt the connection, which can be exploite...

In GNOME glib-networking through 2.64.2 the implementation of GTlsClientConnection skips hostname verification of the server's TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior to fail the certificate verification. Applications that fail to provide the server identity including Balsa before 2.5.11 and 2.6.x before 2.6.1 accept a TLS certificate if the certificate is valid for any host.
