CVE-2026-55558 aiosmtplib: STARTTLS response injection

aiosmtplib is an asynchronous SMTP client for use with asyncio. Prior to 5.1.2, SMTPProtocol.starttls in src/aiosmtplib/protocol.py consumes the server's 220 response and starts the TLS handshake without clearing SMTPProtocol.buffer. An active network attacker can place attacker-chosen SMTP...

CVE-2026-68552

Coturn versions before 4.15.0 have a uint16_t overflow in stun_get_message_len_str() in src/client/ns_turn_msg.c: a crafted STUN body-length (65520–65532) causes the variable to wrap when STUN_HEADER_LENGTH is added, desynchronizing the TCP/TLS stream parser and dropping only the attacker's conne...
