Descriptions

Sofia-SIP is an open-source Session Initiation Protocol (SIP) User-Agent library. Prior to version 1.13.8, when parsing each line of a sdp message, `rest = record + 2` will access the memory behind `\0` and cause an out-of-bounds write. An attacker can send a message with evil sdp to FreeSWITCH, causing a crash or more serious consequence, such as remote code execution. Version 1.13.8 contains a patch for this issue.

Sofia-SIP es una biblioteca de agente de usuario del Protocolo de Iniciación de Sesión (SIP) de código abierto. En versiones anteriores a 1.13.8, cuando es analizada cada línea de un mensaje sdp, "rest = record + 2" accedía a la memoria detrás de "\0" y causaba una escritura fuera de límites. Un atacante puede enviar un mensaje con sdp maligno a FreeSWITCH, causando un bloqueo o una consecuencia más grave, como una ejecución remota de código. La versión 1.13.8 contiene un parche para este problema
