rustls network-reachable panic in `Acceptor::accept`

A bug introduced in rustls 0.23.13 leads to a panic if the received TLS ClientHello is fragmented. Only servers that use rustls::server::Acceptor::accept are affected. Servers that use tokio-rustls's LazyConfigAcceptor API are affected. Servers that use tokio-rustls's TlsAcceptor API are not...

The vulnerability of the ip6_fragment() function in the Linux operating system’s IPv6 kernel implementation allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the ip6fragment function in the net/ipv6/ip6output.c module of the Linux operating system’s IPv6 kernel implementation is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrit...
