Descriptions

Sofia-SIP is an open-source Session Initiation Protocol (SIP) User-Agent library. Prior to version 1.13.8, an attacker can send a message with evil sdp to FreeSWITCH, which may cause crash. This type of crash may be caused by `#define MATCH(s, m) (strncmp(s, m, n = sizeof(m) - 1) == 0)`, which will make `n` bigger and trigger out-of-bound access when `IS_NON_WS(s[n])`. 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, un atacante puede enviar un mensaje con sdp maligno a FreeSWITCH, lo que puede causar un bloqueo. Este tipo de bloqueo puede ser causado por "#define MATCH(s, m) (strncmp(s, m, n = sizeof(m) - 1) == 0)", que hará que "n" sea más grande y desencadenará un acceso fuera de límites cuando "IS_NON_WS(s[n])". La versión 1.13.8 contiene un parche para este problema
