TLS 1.3 client skips server authentication when ServerHello carries an unsolicited pre_shared_key extension
Key Exchange without Entity Authentication vulnerability in Erlang/OTP ssl allows a peer that answers a TLS 1.3 client connection to impersonate the intended server. A pre_shared_key extension in the ServerHello that the client never offered causes the client…

Libslirp: libslirp: heap buffer overflow in dhcpv6/tftp response builders on small interface mtu
A heap-based buffer overflow was found in the DHCPv6 and TFTP response builders of libslirp. When the host is configured with a small interface MTU, a guest-supplied DHCPv6 CLIENTID option or TFTP blksize option can overflow the reply buffer with attacker-con…
