CVE-2012-1090 – kernel: cifs: dentry refcount leak when opening a FIFO on lookup leads to panic on unmount
https://notcve.org/view.php?id=CVE-2012-1090
The cifs_lookup function in fs/cifs/dir.c in the Linux kernel before 3.2.10 allows local users to cause a denial of service (OOPS) via attempted access to a special file, as demonstrated by a FIFO. La función cifs_lookup en fs/cifs/dir.c en el núcleo de Linux anteriores a v3.2.10 permite a usuarios locales causar una denegación de servicio (OOPS) a través de intentos de acceso a un archivo especial, como lo demuestra un FIFO. • http://lists.opensuse.org/opensuse-security-announce/2012-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2012-05/msg00013.html http://rhn.redhat.com/errata/RHSA-2012-0481.html http://rhn.redhat.com/errata/RHSA-2012-0531.html http://secunia.com/advisories/48842 http://secunia.com/advisories/48964 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.10 http://www.openwall.com/lists/oss-security/2012/02/28/4 https://bugzilla.redhat.com/show • CWE-20: Improper Input Validation •
CVE-2012-1146
https://notcve.org/view.php?id=CVE-2012-1146
The mem_cgroup_usage_unregister_event function in mm/memcontrol.c in the Linux kernel before 3.2.10 does not properly handle multiple events that are attached to the same eventfd, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by registering memory threshold events. La función mem_cgroup_usage_unregister_event en mm/memcontrol.c en el núcleo de Linux anteriores a v3.2.10 no maneja apropiadamente múltiples eventos que son asociados al mismo eventfd, lo cual permite a usuarios locales causar una denegación de servicio (puntero nulo sin referencia y caída del sistema) o posiblemente tener un impacto no especificado por el registro de eventos en el límite de la memoria. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=371528caec553785c37f73fa3926ea0de84f986f http://lists.fedoraproject.org/pipermail/package-announce/2012-March/075781.html http://lists.opensuse.org/opensuse-security-announce/2012-04/msg00021.html http://secunia.com/advisories/48898 http://secunia.com/advisories/48964 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.10 http://www.openwall.com/lists/oss-security/2012/03/07/3 https://bugzilla.redhat • CWE-476: NULL Pointer Dereference •
CVE-2012-0879 – kernel: block: CLONE_IO io_context refcounting issues
https://notcve.org/view.php?id=CVE-2012-0879
The I/O implementation for block devices in the Linux kernel before 2.6.33 does not properly handle the CLONE_IO feature, which allows local users to cause a denial of service (I/O instability) by starting multiple processes that share an I/O context. La implementación I/O para dispositivos de bloque en el núcleo de Linux anteriores a v2.6.33 no maneja adecuadamente la característica CLONE_IO, lo cual permite a usuarios locales causar una denegación de servicio (inestabilidad I/O) arrancando múltiples procesos que comparten un contexto I/O. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.33 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=61cc74fbb87af6aa551a06a370590c9bc07e29d9 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b69f2292063d2caf37ca9aec7d63ded203701bf3 http://lists.opensuse.org/opensuse-security-announce/2012-05/msg00013.html http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://rhn.redhat.com/errata/RHSA-2012-0481.html http://rhn • CWE-400: Uncontrolled Resource Consumption •
CVE-2010-3865 – kernel: iovec integer overflow in net/rds/rdma.c
https://notcve.org/view.php?id=CVE-2010-3865
Integer overflow in the rds_rdma_pages function in net/rds/rdma.c in the Linux kernel allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a crafted iovec struct in a Reliable Datagram Sockets (RDS) request, which triggers a buffer overflow. Desbordamiento de enteros en la función rds_rdma_pages en net/rds/rdma.c en el núcleo de Linux permite a usuarios locales causar una denegación de servicio (caída) y posiblemente ejecutar código de su elección a través de una estructura iovec manipulada en una petición Reliable Datagram Sockets (RDS), que provoca un desbordamiento de búfer. • http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://secunia.com/advisories/42778 http://secunia.com/advisories/42789 http://secunia.com/advisories/42801 http://secunia.com/advisories/42890 http://secunia.com/advisories/46397 http://www.ope • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •
