Se ha descubierto una vulnerabilidad de tipo desbordamiento de búfer en Asterisk 1.2.x versión anterior a 1.2.9 y en la rama 1.0.x versión anterior a 1.0.11. La vulnerabilidad reside en un error en el driver del canal IAX2 (chan_iax2) al realizar el cálculo de longitud de datos suministrados por el usuario. Un atacante remoto podría causar una denegación de servicio y posiblemente ejecutar código arbitrario mediante frames de video IAX 2 (IAX2) especialmente diseñados. Nota: el fabricante solo reconoce que la denegación de servicio es posible pero el investigador es fiable. |
