Descriptions
The load_mixer_volumes function in sound/oss/soundcard.c in the OSS sound subsystem in the Linux kernel before 2.6.37 incorrectly expects that a certain name field ends with a '\0' character, which allows local users to conduct buffer overflow attacks and gain privileges, or possibly obtain sensitive information from kernel memory, via a SOUND_MIXER_SETLEVELS ioctl call.
La función load_mixer_volumes en sound/oss/soundcard.c en el subsistema de sonido OSS del núcleo Linux anterior a v2.6.37 espera incorrectamente a que determinado nombre de campo termine con un carácter '\0', lo que permite a usuarios locales llevar a cabo ataques de desbordamiento de búfer y obtener privilegios o, posiblemente, obtener información sensible de la memoria del núcleo, a través de una llamada SOUND_MIXER_SETLEVELS ioctl.
