A flaw was found in OpenSIPS. An out-of-bounds read vulnerability in the rtpproxy module allows a remote attacker to cause a Denial of Service (DoS) or access sensitive memory contents. By sending specially crafted requests handled by the rtpproxy offer and answer functions, an attacker can cause the service to read beyond allocated memory boundaries, leading to an application crash or information disclosure.
