CVSS: 6.6EPSS: 0%CPEs: 12EXPL: 0CVE-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 •

https://notcve.org/view.php?id=CVE-2011-2492
The bluetooth subsystem in the Linux kernel before 3.0-rc4 does not properly initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel memory via a crafted getsockopt system call, related to (1) the l2cap_sock_getsockopt_old function in net/bluetooth/l2cap_sock.c and (2) the rfcomm_sock_getsockopt_old function in net/bluetooth/rfcomm/sock.c. El subsistema de bluetooth en el kernel de Linux anteriores a v3.0-rc4 no inicializa correctamente algunas estructuras de datos, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de una llamada getsockopt manipulada, en relación con (1) la función l2cap_sock_getsockopt_old en net/bluetooth/l2cap_sock.c y (2) la función rfcomm_sock_getsockopt_old en net/bluetooth/rfcomm/sock.c. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=8d03e971cf403305217b8e62db3a2e5ad2d6263f http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://permalink.gmane.org/gmane.linux.bluez.kernel/12909 http://rhn.redhat.com/errata/RHSA-2011-0927.html http://securitytracker.com/id?1025778 http://www.kernel.org/pub/linux/kernel/v3.0/testing/ChangeLog-3.0-rc4 http://www.openwall.com/lists/oss-security/2011/06/24/2 http://www.openwall.com/lists/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
