CVE-2014-8086 – Kernel: fs: ext4 race condition
https://notcve.org/view.php?id=CVE-2014-8086
Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag. Condición de carrera en la función ext4_file_write_iter en fs/ext4/file.c en el kernel de Linux hasta 3.17 permite a usuarios locales causar una denegación de servicio (no disponibilidad de ficheros) a través de una combinación de una acción de escritura y una operación F_SETFL fcntl para el indicador O_DIRECT. A race condition flaw was found in the Linux kernel's ext4 file system implementation that allowed a local, unprivileged user to crash the system by simultaneously writing to a file and toggling the O_DIRECT flag using fcntl(F_SETFL) on that file. • http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA-2015-0694.html http://www.openwall.com/lists/oss-security/2014/10/09/25 http://www.securityfocus.com/bid/70376 http://www.spinics.net/lists/linux-ext4/msg45683.html http://www.spinics.net/lists/linux-ext4/msg45685.html https://bugzilla.redhat.com/show_bug.cgi?id=1151353 https://exchange.xforce.ibmcloud.com/vulnerabi • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2012-6657 – Kernel: net: guard tcp_set_keepalive against crash
https://notcve.org/view.php?id=CVE-2012-6657
The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5.7 does not ensure that a keepalive action is associated with a stream socket, which allows local users to cause a denial of service (system crash) by leveraging the ability to create a raw socket. La función sock_setsockopt en net/core/sock.c en el kernel de Linux anterior a 3.5.7 no asegura que una acción keepalive está asociada con un socket de flujo, lo que permite a usuarios locales causar una denegación de servicio (caída del sistema) mediante el aprovechamiento de la habilidad de crear un socket en bruto. It was found that the Linux kernel's networking implementation did not correctly handle the setting of the keepalive socket option on raw sockets. A local user able to create a raw socket could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=3e10986d1d698140747fcfc2761ec9cb64c1d582 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://marc.info/?l=bugtraq&m=142722450701342&w=2 http://marc.info/?l=bugtraq&m=142722544401658&w=2 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.5.7 http://www.openwall.com/lists/oss-security/2014/09 • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2014-6418

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly validate auth replies, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via crafted data from the IP address of a Ceph Monitor. net/ceph/auth_x.c en Ceph, utilizado en el kernel de Linux anterior a 3.16.3, no valida debidamente las respuestas de autor válidas, lo que permite a atacantes remotos causar una denegación de servicio (caída del sistema) o posiblemente tener otro impacto no especificado a través de datos manipulados de la dirección IP de un monitor Ceph. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c27a3e4d667fdcad3db7b104f75659478e0c68d8 http://tracker.ceph.com/issues/8979 http://tracker.ceph.com/issues/9561 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.3 http://www.openwall.com/lists/oss-security/2014/09/15/7 http://www.ubuntu.com/usn/USN-2376-1 http://www.ubuntu.com/usn/USN-2377-1 http://www.ubuntu.com/usn/USN-2378-1 http://www.ubuntu.com/usn/USN • CWE-399: Resource Management Errors •
CVE-2014-3184 – Kernel: HID: off by one error in various _report_fixup routines
https://notcve.org/view.php?id=CVE-2014-3184
The report_fixup functions in the HID subsystem in the Linux kernel before 3.16.2 might allow physically proximate attackers to cause a denial of service (out-of-bounds write) via a crafted device that provides a small report descriptor, related to (1) drivers/hid/hid-cherry.c, (2) drivers/hid/hid-kye.c, (3) drivers/hid/hid-lg.c, (4) drivers/hid/hid-monterey.c, (5) drivers/hid/hid-petalynx.c, and (6) drivers/hid/hid-sunplus.c. Las funciones report_fixup en el subsistema HID en el kernel de Linux anterior a 3.16.2 podrían permitir a atacantes físicamente próximos causar una denegación de servicio (escritura fuera de rango) a través de un dispositivo manipulado que proporciona un descriptor de informes pequeño, relacionado con (1) drivers/hid/hid-cherry.c, (2) drivers/hid/hid-kye.c, (3) drivers/hid/hid-lg.c, (4) drivers/hid/hid-monterey.c, (5) drivers/hid/hid-petalynx.c, y (6) drivers/hid/hid-sunplus.c. Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4ab25786c87eb20857bbb715c3ae34ec8fd6a214 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/msg00020.html http://rhn.redhat.com/errata/RHSA-2014-1318.html http://rhn.redhat.com/errata/RHSA • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-193: Off-by-one Error •
CVE-2014-3182 – Kernel: HID: logitech-dj OOB array access
https://notcve.org/view.php?id=CVE-2014-3182
Array index error in the logi_dj_raw_event function in drivers/hid/hid-logitech-dj.c in the Linux kernel before 3.16.2 allows physically proximate attackers to execute arbitrary code or cause a denial of service (invalid kfree) via a crafted device that provides a malformed REPORT_TYPE_NOTIF_DEVICE_UNPAIRED value. Error en el indice del arry en la función logi_dj_raw_event en drivers/hid/hid-logitech-dj.c en el kernel de Linux anterior a 3.16.2 permite a atacantes físicamente próximos ejecutar código arbitrario o causar una denegación de servicio (kfree inválido) a través de un dispositivo manipulado que proporciona un valor REPORT_TYPE_NOTIF_DEVICE_UNPAIRED malformado. An out-of-bounds read flaw was found in the way the Logitech Unifying receiver driver handled HID reports with an invalid device_index value. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ad3e14d7c5268c2e24477c6ef54bbdf88add5d36 http://rhn.redhat.com/errata/RHSA-2014-1318.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.2 http://www.openwall.com/lists/oss-security/2014/09/11/21 http://www.securityfocus.com/bid/69770 https://bugzilla.redhat.com/show_bug.cgi?id=1141210 https://code.google.com/p/google-security-research/issues/detail?id=89 https://github.com/t • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
