CVE-2013-1792 – Kernel: keys: race condition in install_user_keyrings()
https://notcve.org/view.php?id=CVE-2013-1792
Race condition in the install_user_keyrings function in security/keys/process_keys.c in the Linux kernel before 3.8.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) via crafted keyctl system calls that trigger keyring operations in simultaneous threads. Condición de carrera en la función install_user_keyrings en ??security/keys/process_keys.c en el kernel de Linux anterior a v3.8.3 que permite a usuarios locales provocar una denegación de servicio (desreferencia puntero NULL y caída del sistema) a través de la manipulación del sistema keyctl que dispara operaciones de verificación simultáneamente en varios hilos. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=0da9dfdd2cd9889201bc6f6f43580c99165cd087 http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00002.html http://rhn.redhat.com/errata/RHSA-2013-0744.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.8.3 http://www.mandriva.com/security/advisories?name=MDVSA-2013:176 http://www.openwall.com/lists/oss-security/2013 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2013-1798 – kernel: kvm: out-of-bounds access in ioapic indirect register reads
https://notcve.org/view.php?id=CVE-2013-1798
The ioapic_read_indirect function in virt/kvm/ioapic.c in the Linux kernel through 3.8.4 does not properly handle a certain combination of invalid IOAPIC_REG_SELECT and IOAPIC_REG_WINDOW operations, which allows guest OS users to obtain sensitive information from host OS memory or cause a denial of service (host OS OOPS) via a crafted application. La función ioapic_read_indirect virt/kvm/ioapic.c en el kernel de Linux hasta v3.8.4 no controla correctamente una determinada combinación de IOAPIC_REG_SELECT inválida y operaciones IOAPIC_REG_WINDOW, permitiendo a usuarios invitados del SO obtener información confidencial de la memoria principal o causar una denegación de servicio a través de una aplicación diseñada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a2c118bfab8bc6b8bb213abfc35201e441693d55 http://lists.opensuse.org/opensuse-security-announce/2013-05/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2013-06/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2013-07/msg00018.html http://packetstormsecurity.com/files/157233/Kernel-Live-Patch-Security-Notice-LSN-0065-1.html http://rhn.redhat.com/errata/RHSA-2013-0727.html http://rhn.redhat& • CWE-20: Improper Input Validation •
CVE-2013-1860 – kernel: usb: cdc-wdm buffer overflow triggered by device
https://notcve.org/view.php?id=CVE-2013-1860
Heap-based buffer overflow in the wdm_in_callback function in drivers/usb/class/cdc-wdm.c in the Linux kernel before 3.8.4 allows physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted cdc-wdm USB device.
