Race condition in the ecryptfs_mount function in fs/ecryptfs/main.c in the eCryptfs subsystem in the Linux kernel before 3.1 allows local users to bypass intended file permissions via a mount.ecryptfs_private mount with a mismatched uid. Condición de carrera en la función ecryptfs_mount en fs/ecryptfs/main.c en el subsistema eCryptfs en el Kernel de Linux anteriores a v3.1 permite a usuarios locales evitar los permisos de ficheros impuestos a través de montar una unidad con mount.ecryptfs_private con un uid que no coincide. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=764355487ea220fdc2faf128d577d7f679b91f97 http://lists.opensuse.org/opensuse-security-announce/2011-08/msg00009.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.1 http://www.ubuntu.com/usn/USN-1188-1 https://bugzilla.redhat.com/show_bug.cgi?id=731172 https://github.com/torvalds/linux/commit/764355487ea220fdc2faf128d577d7f679b91f97 https://access.redhat.com/security/cve/CVE-2011-1833 • CWE-264: Permissions, Privileges, and Access Controls CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

The qdisc_notify function in net/sched/sch_api.c in the Linux kernel before 2.6.35 does not prevent tc_fill_qdisc function calls referencing builtin (aka CQ_F_BUILTIN) Qdisc structures, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a crafted call. La función qdisc_notify de net/sched/sch_api.c del kernel de Linux en versiones anteriores a la 2.6.35 no previene que la función tc_fill_qdisc haga referencia a estructuras Qdisc (CQ_F_BUILTIN) pre-construídas, lo que permite a usuarios locales provocar una denegación de servicio (resolución de puntero NULL y OOPS) o posiblemente tener otros impactos sin especificar a través de una llamada modificada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=53b0f08042f04813cd1a7473dacd3edfacb28eb3 http://kerneltrap.org/mailarchive/linux-netdev/2010/5/21/6277805 http://mirror.anl.gov/pub/linux/kernel/v2.6/ChangeLog-2.6.35 http://openwall.com/lists/oss-security/2011/07/12/1 http://rhn.redhat.com/errata/RHSA-2011-1065.html http://rhn.redhat.com/errata/RHSA-2011-1163.html https://bugzilla.redhat.com/show_bug.cgi?id=720552 https://access.redhat. • CWE-476: NULL Pointer Dereference •

The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before 3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of the block size, which allows local users to cause a denial of service (BUG and system crash) by arranging for all resource groups to have too little free space.
