Descriptions

An issue was discovered in Teluu pjproject (pjlib and pjlib-util) in PJSIP before 2.7.1. The ioqueue component may issue a double key unregistration after an attacker initiates a socket connection with specific settings and sequences. Such double key unregistration will trigger an integer overflow, which may cause ioqueue backends to reject future key registrations.

Se ha descubierto un error en Teluu pjproject (pjlib y pjlib-util) en PJSIP, en versiones anteriores a la 2.7.1. El componente ioqueue puede enviar una anulación del registro de una clave doble después de que un atacante inicie una conexión de socket con ajustes y secuencias específicos. Esta anulación de registro de clave doble desencadenará un desbordamiento de enteros, lo que puede provocar que los backends de ioqueue rechacen futuros registros de claves.
