Description |
|
|
Se ha descubierto una vulnerabilidad de tipo condición de carrera en el sistema de ficheros OpenAFS en la rama 1.3 versiones 1.3.50 y posteriores, en la rama 1.4 versiones anteriores a la 1.4.5 y en la rama 1.5 versiones anteriores a la 1.5.27. La vulnerabilidad reside en que si simultáneamente se bloquean y desbloquean ficheros el gestor "GiveUpAllCallBacks RPC" realizaría ciertas operaciones sin la opción de bloqueo "host_glock" lo que causaría una condición de carrera. Un atacante remoto podría causar una denegación de servicio. |
