The xfs implementation in the Linux kernel before 2.6.35 does not look up inode allocation btrees before reading inode buffers, which allows remote authenticated users to read unlinked files, or read or overwrite disk blocks that are currently assigned to an active file but were previously assigned to an unlinked file, by accessing a stale NFS filehandle. La implementación xfs en el kernel Linux, en versiones anteriores a la 2.6.35, no busca la asignación de inodes btrees antes de leer los búfer inode, lo que permite a atacantes remotos autenticados leer ficheros no enlazados o leer o sobreescribir bloques de disco que están asignados actualmente a un fichero activo pero que fueron previamente asignados a un fichero no enlazado, accediendo a un manejador de fichero NFS antiguo. • https://www.exploit-db.com/exploits/15155 http://article.gmane.org/gmane.comp.file-systems.xfs.general/33767 http://article.gmane.org/gmane.comp.file-systems.xfs.general/33768 http://article.gmane.org/gmane.comp.file-systems.xfs.general/33769 http://article.gmane.org/gmane.comp.file-systems.xfs.general/33771 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1920779e67cbf5ea8afef317777c5bf2b8096188 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The actions implementation in the network queueing functionality in the Linux kernel before 2.6.36-rc2 does not properly initialize certain structure members when performing dump operations, which allows local users to obtain potentially sensitive information from kernel memory via vectors related to (1) the tcf_gact_dump function in net/sched/act_gact.c, (2) the tcf_mirred_dump function in net/sched/act_mirred.c, (3) the tcf_nat_dump function in net/sched/act_nat.c, (4) the tcf_simp_dump function in net/sched/act_simple.c, and (5) the tcf_skbedit_dump function in net/sched/act_skbedit.c. La implementación de acciones en la funcionalidad de encolado de red en el kernel Linx anterior a v2.6.36-rc2 no inicializa apropiadamente ciertos miembros de estructura cuando se realizan acciones de volcado, lo que permite a usuarios locales obtener información potencialmente sensible de la memoria del kernel a través de vectores relacionados con (1) la funcion tcf_gact_dump en net/sched/act_gact.c, (2) la funcion tcf_mirred_dump en net/sched/act_mirred.c, (3) la funcion tcf_nat_dump en net/sched/act_nat.c, (4) la funcion tcf_simp_dump en net/sched/act_simple.c, y (5) la funcion tcf_skbedit_dump en net/sched/act_skbedit.c. • http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.git%3Ba=commit%3Bh=1c40be12f7d8ca1d387510d39787b12e512a7ce8 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2010-12/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://patchwork.oz • CWE-401: Missing Release of Memory after Effective Lifetime •

The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c. La función gfs2_dirent_find_space en fs/gfs2/dir.c en el kernel de Linux anterior a v 2.6.35, usa un valor de tamaño incorrecto en los cálculos asociados con las entradas del directorio "sentinel", lo que permite a usuarios locales provocar una denegación de servicio (deferencia a puntero nullo y kernel panic) y posiblemente otro impacto no especificados mediante el renombrado de un archivo en un sistema de fichero GFS2, relacionado con la función gfs2_rename en fs/gfs2/ops_inode.c. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=728a756b8fcd22d80e2dbba8117a8a3aafd3f203 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00000.html http://secunia.com/advisories/46397 http://securitytracker.com/id?1024386 http://support.avaya.com/css/P8/documents/100113326 http://www.debian.org/security/2010/dsa-2094 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLo • CWE-476: NULL Pointer Dereference •

Buffer overflow in the ecryptfs_uid_hash macro in fs/ecryptfs/messaging.c in the eCryptfs subsystem in the Linux kernel before 2.6.35 might allow local users to gain privileges or cause a denial of service (system crash) via unspecified vectors.
