GHSA-3CCM-4QQ2-5WRP Constrata's coordinator transit engine `ciphertextContainer.UnmarshalJSON` panics on attacker-controlled short ciphertexts

Summary ciphertextContainer.UnmarshalJSON decodes the third :-separated component of a vault:vX:base64... ciphertext and then unconditionally takes a 12-byte prefix slice for the AES-GCM nonce: c.nonce = fullCiphertext:aesGCMNonceSize. If the decoded blob is shorter than 12 bytes, the slice...

CVE-2026-43994

A flaw was found in Coturn, an open-source TURN and STUN server. A remote attacker can exploit a stack buffer overflow vulnerability by providing a specially crafted OAuth access token when the server is configured to use --oauth mode. This could lead to arbitrary code execution RCE, allowing the...

CVE-2026-43994

Coturn is a free open source implementation of TURN and STUN Server. Versions prior to 4.10.0 contain a stack buffer overflow in decodeoauthtokengcm. A uint16t noncelen field read from an attacker-supplied OAuth access token 0-65535 is passed directly to memcpy as the copy length into a 256-byte...

BIT-PGBOUNCER-2026-6665 PgBouncer buffer overflow in SCRAM

The SCRAM code in PgBouncer before 1.25.2 did not check the return value of strlcat correctly when building the contents of the SCRAM client-final-message. A malicious backend that sends a SCRAM server-final-message with a long nonce can trigger a stack overflow...
