The set_pixel_format function in ui/vnc.c in QEMU allows remote attackers to cause a denial of service (crash) via a small bytes_per_pixel value. La función set_pixel_format en ui/vnc.c en QEMU permite a atacantes remotos causar una denegación de servicio (caída) a través de valores pequeños de bytes_per_pixel. An uninitialized data structure use flaw was found in the way the set_pixel_format() function sanitized the value of bits_per_pixel. An attacker able to access a guest's VNC console could use this flaw to crash the guest. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=e6908bfe8e07f2b452e78e677da1b45b1c0f6829 http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00019.html http://rhn.redhat.com/errata/RHSA-2015-0349.html http://rhn.redhat.com/errata/RHSA-2015-0624.html http://secunia.com/advisories/61484 http://secunia.com/advisories/62143 http://secunia.com/advisories/62144 http://support.citrix.com/article/CTX200892 http://www.debian.org/security/2014/dsa-3066 http://www.debian.org/secu • CWE-20: Improper Input Validation •

The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c. La funcionalidad de procesamiento WRMSR en el subsistema KVM en el kernel de Linux hasta 3.17.2 no maneja debidamente la escritura de direcciones no canónicas en un registro especifico a modelos, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo anfitrión) mediante el aprovechamiento de los privilegios del sistema operativo invitado, relacionado con la función wrmsr_interception en arch/x86/kvm/svm.c y la función handle_wrmsr en arch/x86/kvm/vmx.c. It was found that KVM's Write to Model Specific Register (WRMSR) instruction emulation would write non-canonical values passed in by the guest to certain MSRs in the host's context. A privileged guest user could use this flaw to crash the host. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=854e8bb1aa06c578c2c9145fa6bfe3680ef63b23 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-2015-0869.html http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/10/24/9 http://www.securityfocus.com/bid/70742 http://www.ubuntu.com/u • CWE-248: Uncaught Exception •

The donote function in readelf.c in file through 5.20, as used in the Fileinfo component in PHP 5.4.34, does not ensure that sufficient note headers are present, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted ELF file. La función donote en readelf.c en file hasta 5.20, utilizado en el componente Fileinfo en PHP 5.4.34, no asegura que suficientes cabeceras de notas están presentes, lo que permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango y caída de aplicación) a través de un fichero ELF manipulado. An out-of-bounds read flaw was found in the way the File Information (fileinfo) extension parsed Executable and Linkable Format (ELF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted ELF file. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=1803228597e82218a8c105e67975bc50e6f5bf0d http://linux.oracle.com/errata/ELSA-2014-1767.html http://linux.oracle.com/errata/ELSA-2014-1768.html http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.opensuse.org/opensuse-updates/2014-11/msg00113.html http://rhn.redhat.com/errata/RHSA-2014-1765.html http://rhn.redhat.com/errata/RHSA-2014-1766.html http://rhn.redhat.com/errata/RHSA-2014-1767.html http: • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •

Race condition in the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c in the KVM subsystem in the Linux kernel through 3.17.2 allows guest OS users to cause a denial of service (host OS crash) by leveraging incorrect PIT emulation. Condición de carrera en la función __kvm_migrate_pit_timer en arch/x86/kvm/i8254.c en el subsistema KVM en el kernel de Linux hasta 3.17.2 permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo anfitrión) mediante el aprovechamiento de la emulación PIT incorrecta. A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=2febc839133280d5a5e8e1179c94ea674489dae2 http://rhn.redhat.com/errata/RHSA-2015-0126.html http://rhn.redhat.com/errata/RHSA-2015-0284.html http://rhn.redhat.com/errata/RHSA-2015-0869.html http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/10/24/9 http://www.ubuntu.com/usn/USN-2394-1 http://www.ubuntu.com/usn/USN-2417-1 http://www.ubun • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
