Ruby: Net::SMTP with tls allows forged certificates as long as the hostname matches

I'd like to report a very odd behavior I observed in the Net::SMTP module, part of Ruby's standard library. It seems when performing a TLS connection the code checks the certificate hostname, but not the certificate signature or issuer. This of course makes little sense, as an attacker can create...

Missing sanitization in mozwire allows local file overwrite of files ending in .conf

The client software downloaded a list of servers from mozilla's servers and created local files named after the hostname field in the json document. No verification of the content of the string was made, and it could therefore have included '../' leading to path traversal. This allows an attacker...

In the GNU C Library (aka glibc or libc6) through 2.28 attempting to resolve a crafted hostname via getaddrinfo() leads to the allocation of a socket descriptor that is not closed. This is related to the if_nametoindex() function.

...

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.
