https://notcve.org/view.php?id=CVE-2014-8709
The ieee80211_fragment function in net/mac80211/tx.c in the Linux kernel before 3.13.5 does not properly maintain a certain tail pointer, which allows remote attackers to obtain sensitive cleartext information by reading packets. La función ieee80211_fragment en net/mac80211/tx.c en el kernel de Linux anterior a 3.13.5 no mantiene debidamente cierto puntero de cola, lo que permite a atacantes remotos obtener información sensible en texto plano mediante la lectura de paquetes. An information leak flaw was found in the Linux kernel's IEEE 802.11 wireless networking implementation. When software encryption was used, a remote attacker could use this flaw to leak up to 8 bytes of plaintext. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=338f977f4eb441e69bb9a46eaa0ac715c931a67f 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://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA-2015-1272.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeL • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 1CVE-2014-7826 – kernel: insufficient syscall number validation in perf and ftrace subsystems
https://notcve.org/view.php?id=CVE-2014-7826
kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the ftrace subsystem, which allows local users to gain privileges or cause a denial of service (invalid pointer dereference) via a crafted application. kernel/trace/trace_syscalls.c en el kernel de Linux hasta 3.17.2 no maneja debidamente los números privados de las llamadas al sistema durante el uso del subsistema ftrace, lo que permite a usuarios locales ganar privilegios o causar una denegación de servicio (referencia a puntero inválido) a través de una aplicación manipulada. An out-of-bounds memory access flaw, CVE-2014-7825, was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system. Additionally, an out-of-bounds memory access flaw, CVE-2014-7826, was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=086ba77a6db00ed858ff07451bedee197df868c9 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://rhn.redhat.com/errata/RHSA-2014-1943.html http://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA-2015-0864.html http://www.openwall.com/lists/oss-security/2014/11/06/11 http:// • CWE-476: NULL Pointer Dereference •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 2CVE-2014-8369 – kernel: kvm: excessive pages un-pinning in kvm_iommu_map error path
https://notcve.org/view.php?id=CVE-2014-8369
The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.17.2 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges. NOTE: this vulnerability exists because of an incorrect fix for CVE-2014-3601. La función kvm_iommu_map_pages en virt/kvm/iommu.c en el kernel de Linux hasta 3.17.2 calcula mal el número de páginas durante el manejo de fallo en el mapeo, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio ( liberación de página del sistema operativo anfitrión) o posiblemente tener otro impacto no especificado mediante el aprovechamiento de los privilegios del sistema operativo invitado. NOTA: esta vulnerabilidad existe debido a una solución incorrecta para CVE-2014-3601. It was found that the fix for CVE-2014-3601 was incomplete: the Linux kernel's kvm_iommu_map_pages() function still handled IOMMU mapping failures incorrectly. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=3d32e4dbe71374a6780eaf51d719d76f9a9bf22f 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://rhn.redhat.com/errata/RHSA-2015-0674.html http://secunia.com/advisories/62326 http://secunia.com/advisories/62336 http://www.debian.org/security/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
