"value": "PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming STUN message contains an ERROR-CODE attribute, the header length is not checked before performing a subtraction operation, potentially resulting in an integer underflow scenario. This issue affects all users that use STUN. A malicious actor located within the victim\u2019s network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victim\u2019s machine. Users are advised to upgrade as soon as possible. There are no known workarounds."

En las versiones afectadas, si el mensaje STUN entrante contiene un atributo ERROR-CODE, no se comprueba la longitud del encabezado antes de llevar a cabo una operaci\u00f3n de sustracci\u00f3n, resultando en un escenario de desbordamiento de enteros. Este problema afecta a todos los usuarios que usan STUN. Un actor malicioso situado en la red de la v\u00edctima puede falsificar y enviar un mensaje UDP (STUN) especialmente dise\u00f1ado que podr\u00eda ejecutar remotamente c\u00f3digo arbitrario en la m\u00e1quina de la v\u00edctima. Se aconseja a usuarios que actualicen lo antes posible. No se presentan soluciones conocidas"
