CVSS: 6.9EPSS: 0%CPEs: 51EXPL: 1CVE-2015-3214 – QEMU - Programmable Interrupt Timer Controller Heap Overflow
https://notcve.org/view.php?id=CVE-2015-3214
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. Vulnerabilidad en pit_ioport_read en i8254.c en el kernel de Linux en versiones anteriores a 2.6.33 y en QEMU en versiones anteriores a 2.3.1, no distingue entre longitudes de lectura y longitudes de escritura, lo que podría permitir a los usuarios invitados del SO ejecutar código arbitrario en el host del SO desencadenando el uso de un índice no válido. An out-of-bounds memory access flaw, leading to memory corruption or possibly an information leak, was found in QEMU's pit_ioport_read() function. A privileged guest user in a QEMU guest, which had QEMU PIT emulation enabled, could potentially, in rare cases, use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. • https://www.exploit-db.com/exploits/37990 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ee73f656a604d5aa9df86a97102e4e462dd79924 http://mirror.linux.org.au/linux/kernel/v2.6/ChangeLog-2.6.33 http://rhn.redhat.com/errata/RHSA-2015-1507.html http://rhn.redhat.com/errata/RHSA-2015-1508.html http://rhn.redhat.com/errata/RHSA-2015-1512.html http://www.debian.org/security/2015/dsa-3348 http://www.openwall.com/lists/oss-security/2015/06/25/7 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.2EPSS: 0%CPEs: 5EXPL: 1CVE-2015-3290 – Linux Kernel - 'espfix64' Nested NMIs Interrupting Privilege Escalation
https://notcve.org/view.php?id=CVE-2015-3290
arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform improperly relies on espfix64 during nested NMI processing, which allows local users to gain privileges by triggering an NMI within a certain instruction window. Vulnerabilidad en arch/x86/entry/entry_64.S en el kernel de Linux en versiones anteriores a 4.1.6 en la plataforma x86_64, confía indebidamente en espfix64 durante el procesamiento anidado de NMI, lo que permite a usuarios locales obtener privilegios al desencadenar una NMI dentro de una cierta ventana de instrucción.

arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform does not properly determine when nested NMI processing is occurring, which allows local users to cause a denial of service (skipped NMI) by modifying the rsp register, issuing a syscall instruction, and triggering an NMI. Vulnerabilidad en arch/x86/entry/entry_64.S en el kernel de Linux en versiones anteriores a 4.1.6 en la plataforma x86_64, no determina correctamente cuándo está ocurriendo el procesamiento anidado de NMI, lo que permite a usuarios locales causar una denegación de servicio (NMI saltada) modificando el registro rsp, causando una llamada de instrucción del sistema y desencadenando una NMI. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=810bc075f78ff2c221536eb3008eac6a492dba2d http://www.debian.org/security/2015/dsa-3313 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.1.6 http://www.openwall.com/lists/oss-security/2015/07/22/7 http://www.securityfocus.com/bid/76003 http://www.ubuntu.com/usn/USN-2687-1 http://www.ubuntu.com/usn/USN-2688-1 http://www.ubuntu.com/usn/USN-2689-1 http://www.ubuntu.com/usn • CWE-17: DEPRECATED: Code •

https://notcve.org/view.php?id=CVE-2015-5157
arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform mishandles IRET faults in processing NMIs that occurred during userspace execution, which might allow local users to gain privileges by triggering an NMI. Vulnerabilidad en arch/x86/entry/entry_64.S en el kernel de Linux en versiones anteriores a 4.1.6 en la plataforma x86_64, no maneja correctamente los fallos IRET procesando NMIs que ocurrieron durante la ejecución en el espacio de usuario, lo que puede permitir a usuarios locales obtener privilegios mediante desencadenamiento de una NMI. A flaw was found in the way the Linux kernel handled IRET faults during the processing of NMIs. An unprivileged, local user could use this flaw to crash the system or, potentially (although highly unlikely), escalate their privileges on the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9b6e6a8334d56354853f9c255d1395c2ba570e0a http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00013.html http://rhn.redhat.com • CWE-264: Permissions, Privileges, and Access Controls CWE-435: Improper Interaction Between Multiple Correctly-Behaving Entities •

https://notcve.org/view.php?id=CVE-2015-5366
The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 provide inappropriate -EAGAIN return values, which allows remote attackers to cause a denial of service (EPOLLET epoll application read outage) via an incorrect checksum in a UDP packet, a different vulnerability than CVE-2015-5364. Vulnerabilidad en las funciones (1) udp_recvmsg y (2) udpv6_recvmsg en el kernel de Linux en versiones anteriores a 4.0.6, proporcionan valores de retorno -EAGAIN inapropiados, lo que permite a atacantes remotos causar una denegación de servicio (interrupción de lectura de EPOLLET en aplicación epoll) a través de una suma de comprobación incorrecta en un paquete UDP, una vulnerabilidad diferente a CVE-2015-5364. A flaw was found in the way the Linux kernel's networking implementation handled UDP packets with incorrect checksum values. A remote attacker could potentially use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service on the system, or cause a denial of service in applications using the edge triggered epoll functionality. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=beb39db59d14990e401e235faf66a6b9b31240b0 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10761 http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://lists.opensuse.org/opensuse&# • CWE-399: Resource Management Errors CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
