Descriptions

Race condition in the find_keyring_by_name function in security/keys/keyring.c in the Linux kernel 2.6.34-rc5 and earlier allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via keyctl session commands that trigger access to a dead keyring that is undergoing deletion by the key_cleanup function.

Condición de carrera en la función find_keyring_by_name en security/keys/keyring.c el el kernel de Linux v2.6.34-rc5 y anteriores, permite usuarios locales provocar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente tener otros impactos, mediante comandos de sesión "keyctl" que provocan el acceso a una secuencia de pulsaciones en desuso que está bajo un borrado en la función key_cleanup.
