CVE-2026-45538
OpenSIPS is a Session Initiation Protocol SIP server implementation. In versions 4.0.0 and prior, processing a SIP message with a header name longer than 255 bytes causes a stack buffer overflow when siptojson is called in the routing script. Function siptojson modules/sipmsgops/sipmsgops.c copie...
CVE-2026-45538
OpenSIPS prior to 4.0.0 is vulnerable to a stack buffer overflow in sip_to_json() when processing a SIP header name longer than 255 bytes. The function copies header names into a fixed 255-byte stack buffer without bounds checking, even though header names can be ~65,000 bytes. A routing script t...
ldns: ldns: Off-path poisoning attacks due to insufficient query-response matching
A flaw was found in ldns. When applications use ldns as a resolver over User Datagram Protocol UDP, it fails to properly match the query's destination address and port with the response's source address and port. Additionally, the query ID and question are not matched with the response. This...
netty-resolver-dns: Netty DNS resolver: DNS Cache Poisoning via predictable transaction IDs
A flaw was found in Netty's DNS resolver component. This vulnerability arises from the use of a predictable pseudo-random number generator PRNG for DNS transaction IDs and a static User Datagram Protocol UDP source port. This combination significantly reduces the randomness of DNS queries, making...

CVE-2026-54609
QTI Neon is a minimal, game-agnostic, relay-based UDP multiplayer protocol library. In version 1.0.0, the relay's handleReconnectRequest forwards RECONNECTREQUEST packets to the host without bounding them, so an unauthenticated client can drive relay-to-host amplification and cause a denial of...
CVE-2026-55990 Packet of death for a DNSCrypt misconfigured Unbound
In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, when the 'dnscrypt:' clause lists more 'dnscrypt-provider-cert:' files than there are matching 'dnscrypt-secret-key:' files, Unbound fills only the matched prefix and leaves the tail slots at the '0xdb' fill that libsodium's allocator writes...
EUVD-2026-47678
In NLnet Labs Unbound 1.18.0 up to and including 1.25.1, when Unbound listens on a 'proxy-protocol-port' interface with 'answer-cookie: yes', the RFC 9018 server-cookie SipHash is computed over the proxy's wire address instead of the PROXYv2-declared client. One server cookie obtained through a...

CVE-2026-50252
In NLnet Labs Unbound 1.4.22 up to and including 1.25.1, UDP source port is randomized and intended to serve as a secret value that increases the entropy of DNS transactions. When resolver load balancing policies depend on the source port while their outcome is revealed this secrecy is undermined...
