SUSE CVE-2026-40613

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.10.0, the STUN/TURN attribute parsing functions in coturn perform unsafe pointer casts from uint8t to uint16t without alignment checks. When processing a crafted STUN message with odd-aligned attribute boundaries, thi...

CVE-2026-68555

A flaw was found in Coturn. An authenticated user can exploit a vulnerability in the mobility feature when it is enabled. By repeatedly initiating and resuming allocations without completing the handoff process, the server's session management is bypassed. This allows the attacker to retain an...

CVE-2026-68552

A flaw was found in Coturn. An unauthenticated remote client can send a specially crafted STUN message over TCP or TLS. This message, with a specific body-length field, causes an integer truncation overflow, leading to the desynchronization of the stream parser. Consequently, the attacking client...

The vulnerability of the send_message_to_redis() function in the hiredis_libevent2.c file of the Coturn web server allows a hacker to trigger a denial-of-service attack and expose sensitive information.

The vulnerability of the sendmessagetoredis function in the hiredislibevent2.c file of the Coturn web server is related to insufficient handling of the format string. Exploiting this vulnerability could allow a remote attacker to cause service failures and expose sensitive information...

CVE-2026-68554

A flaw was found in Coturn, a free open source implementation of TURN and STUN Session Traversal Utilities for NAT Server. An on-path attacker can exploit this vulnerability on plain UDP or TCP by appending attributes after the MESSAGE-INTEGRITY field in an authenticated STUN request. This allows...

CVE-2026-68553

A flaw was found in Coturn. An authenticated TURN user can exploit a format string vulnerability by injecting printf-style format specifiers into the STUN USERNAME or REALM attribute. This can lead to a crash of the coturn process, resulting in a Denial of Service DoS and termination of active TU...

CVE-2026-73212

A flaw was found in Coturn. An authenticated client using the RFC 6062 TCP CONNECT relay path can bypass intended IPv4 denied-peer-ip range restrictions due to improper canonicalization of IPv4-compatible, 6to4, and NAT64 address forms. This vulnerability can lead to Server-Side Request Forgery...

SUSE CVE-2026-68552

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.15.0, an unauthenticated remote client can send a STUN message over TCP or TLS with a body-length field from 65520 through 65532, causing the uint16t len variable in stungetmessagelenstr in src/client/nsturnmsg.c to...

SUSE CVE-2026-68553

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.13.0, an authenticated TURN user can place printf-style format specifiers in the STUN USERNAME or REALM attribute, which passes issecurestring validation and is embedded into Redis keys at nine call sites in...

SUSE CVE-2026-68554

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.15.0, an on-path attacker can append attributes after MESSAGE-INTEGRITY to an authenticated STUN request on plain UDP or TCP, adjust the STUN header length, and recompute the unkeyed FINGERPRINT while the original HMA...

SUSE CVE-2026-68555
