CVE-2014-1738 – kernel: block: floppy: privilege escalation via FDRAWCMD floppy ioctl command
https://notcve.org/view.php?id=CVE-2014-1738
The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device. La función raw_cmd_copyout en drivers/block/floppy.c en el kernel de Linux hasta 3.14.3 no restringe debidamente acceso a ciertos punteros durante el procesamiento de una llamada FDRAWCMD ioctl, lo que permite a usuarios locales obtener información sensible de la memoria dinámica del kernel mediante el aprovechamiento de acceso a escritura hacia un dispositivo /dev/fd. A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important) It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=2145e15e0557a01b9195d1c7199a1b92cb9be81f http://linux.oracle.com/errata/ELSA-2014-0771.html http://linux.oracle.com/errata/ELSA-2014-3043.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00012.html http://rhn.redhat.com/errata/RHSA-2014-0800.html http://rhn.redhat.com/errata/RHSA-2014-0801.html http://secunia.com • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2014-0181 – kernel: net: insufficient permision checks of netlink messages
https://notcve.org/view.php?id=CVE-2014-0181
The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing socket operations based on the opener of a socket, which allows local users to bypass intended access restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr of a setuid program. La implementación Netlink en el kernel de Linux hasta 3.14.1 no proporciona un mecanismo para autorizar operaciones socket basadas en el abridor de un socket, lo que permite a usuarios locales evadir restricciones de acceso y modificar configuraciones de red mediante el uso de un socket Netlink para (1) stdout o (2) stderr de un programa setuid. It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. • http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://marc.info/?l=linux-netdev&m=139828832919748&w=2 http://rhn.redhat.com/errata/RHSA-2014-1959.html http://www.open • CWE-264: Permissions, Privileges, and Access Controls •
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 •
