crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

undici: undici: Man-in-the-Middle attack via ignored TLS options with SOCKS5 proxy

A flaw was found in undici. When undici's ProxyAgent is configured with a SOCKS5 proxy Uniform Resource Identifier URI, it silently ignores Transport Layer Security TLS options, such as custom Certificate Authorities CAs. This allows a remote attacker to perform a Man-in-the-Middle MITM attack,...
