CVE-2010-0727
Estado: ModificadaMedia (4.9)—
La función gfs2_lock en el Linux kernel anterior v2.6.34-rc1-next-20100312, y la función gfs_lock en el Linux kernel de Red Hat Enterprise Linux (RHEL) v5 y v6, no elimina adecuadamente el POSIX locks en los archivos setgid sin permisos group-execute, lo que permite a usuarios locales causar una denegación de servicio (BUG y caída de sistema) bloqueando un archivo en los sistemas de archivos(1) GFS o (2) GFS2, y luego cambiar los permisos de este archivo.
CVSS
- Versión: 2.0
- Vector: AV:L/AC:L/Au:N/C:N/I:N/A:C
- Puntuación base: 4.9
