GHSA-28GM-JRMW-XX93 SIPSorcery: Malformed UDP packet on the RTP/ICE socket can remotely terminate a media session (DoS)

Impact A single malformed inbound UDP packet on the RTP/ICE socket can remotely terminate an active RTP or WebRTC media session. The packet receive handler indexes packet and STUN attribute bytes without sufficient length checks and throws, and the UDP receive loop converted any such exception in...

CVE-2026-11352: Loop with Unreachable Exit Condition

An issue in curl’s QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service against a curl or libcurl client. Because the helper function discards zero-length UDP datagrams before counting them toward the per-call packet budget, a connected QUIC peer can...
