CVE-2014-3601 – kernel: kvm: invalid parameter passing in kvm_iommu_map_pages()
https://notcve.org/view.php?id=CVE-2014-3601
The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn value that leads to permanently pinned pages. La función kvm_iommu_map_pages en virt/kvm/iommu.c en el kernel de Linux hasta 3.16.1 calcula erróneamente el número de las páginas durante el manejo de un fallo en las asignaciones, lo que permite a usuarios del sistema operativo invitado (1) causar una denegación de servicio (corrupción de la memoria del sistema operativo anfitrión) o posiblemente tener otro impacto no especificado mediante la provocación de un valor gfn grande o (2) causar una denegación de servicio (corrupción de la memoria del sistema operativo anfitrión) mediante la provocación de un valor gfn pequeño que conduce a páginas fijadas (pinned) permanentemente. A flaw was found in the way the Linux kernel's kvm_iommu_map_pages() function handled IOMMU mapping failures. A privileged user in a guest with an assigned host device could use this flaw to crash the host. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=350b8bdd689cd2ab2c67c8a86a0be86cfa0751a7 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/msg00015.html http://secunia.com/advisories/60830 http://www.securityfocus.com/bid/69489 http://www.ubuntu.com/usn/USN-2356-1 http://www.ubuntu.com/usn/USN-2357 • CWE-189: Numeric Errors •
CVE-2013-4357

CVE-2014-1739 – Linux Kernel 3.3.5 - '/drivers/media/media-device.c' Local Information Disclosure
https://notcve.org/view.php?id=CVE-2014-1739
The media_device_enum_entities function in drivers/media/media-device.c in the Linux kernel before 3.14.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call. La función media_device_enum_entities en drivers/media/media-device.c en el kernel de Linux anterior a 3.14.6 no inicializa cierta estructura de datos, lo que permite a usuarios locales obtener información sensible de la memoria del kernel mediante el aprovechamiento del acceso a lectura /dev/media0 para una llamada MEDIA_IOC_ENUM_ENTITIES ioctl. An information leak flaw was found in the way the Linux kernel handled media device enumerate entities IOCTL requests. A local user able to access the /dev/media0 device file could use this flaw to leak kernel memory bytes. • https://www.exploit-db.com/exploits/39214 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=e6a623460e5fc960ac3ee9f946d3106233fd28d8 http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00007.html http://secunia.com/advisories/59597 http://speirofr.appspot.com/cve-2014-1739-kernel-infoleak-vulnerability-in-media_enum_entities.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2014-0196 – Linux Kernel Race Condition Vulnerability
https://notcve.org/view.php?id=CVE-2014-0196
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings. La función n_tty_write en drivers/tty/n_tty.c en el kernel de Linux hasta 3.14.3 no maneja debidamente acceso al controlador tty en el caso 'LECHO & !OPOST', lo que permite a usuarios locales causar una denegación de servicio (consumo de memoria y caída de sistema) o ganar privilegios mediante la provocación de una condición de carrera involucrando operaciones de lectura y escritura con cadenas largas. Linux Kernel contains a race condition vulnerability within the n_tty_write function that allows local users to cause a denial-of-service (DoS) or gain privileges via read and write operations with long strings. • https://www.exploit-db.com/exploits/33516 https://github.com/tempbottle/CVE-2014-0196 https://github.com/SunRain/CVE-2014-0196 http://bugzilla.novell.com/show_bug.cgi?id=875690 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4291086b1f081b869c6d79e5b7441633dc3ace00 http://linux.oracle.com/errata/ELSA-2014-0771.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg0001 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
