CVE-2016-3712 – qemu-kvm: Out-of-bounds read when creating weird vga screen surface
https://notcve.org/view.php?id=CVE-2016-3712
Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode. Desbordamiento de entero en el módulo VGA en QEMU permite a usuarios de SO invitado locales provocar una denegación de servicio (lectura fuera de límites y caída de proceso QEMU) editando registros VGA en modo VBE. An integer overflow flaw and an out-of-bounds read flaw were found in the way QEMU's VGA emulator set certain VGA registers while in VBE mode. A privileged guest user could use this flaw to crash the QEMU process instance. • http://rhn.redhat.com/errata/RHSA-2016-2585.html http://rhn.redhat.com/errata/RHSA-2017-0621.html http://support.citrix.com/article/CTX212736 http://www.debian.org/security/2016/dsa-3573 http://www.openwall.com/lists/oss-security/2016/05/09/4 http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http://www.securityfocus.com/bid/90314 http://www.securitytracker.com/id/1035794 http://www.ubuntu.com/usn/USN-2974-1 http://xenbits.xen.org/ • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •
CVE-2016-3710 – qemu: incorrect banked access bounds checking in vga module
https://notcve.org/view.php?id=CVE-2016-3710
The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue. El módulo VGA en QEMU lleva a cabo incorrectamente comprobaciones de límites sobre acceso almacenado a la memoria de vídeo, lo que permite a administradores locales de SO invitado ejecutar código arbitrario sobre el anfitrión cambiando los modos de acceso después de establecer el banco de registros, también conocido como el problema "Dark Portal". An out-of-bounds read/write access flaw was found in the way QEMU's VGA emulation with VESA BIOS Extensions (VBE) support performed read/write operations using I/O port methods. A privileged guest user could use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU process. • http://rhn.redhat.com/errata/RHSA-2016-0724.html http://rhn.redhat.com/errata/RHSA-2016-0725.html http://rhn.redhat.com/errata/RHSA-2016-0997.html http://rhn.redhat.com/errata/RHSA-2016-0999.html http://rhn.redhat.com/errata/RHSA-2016-1000.html http://rhn.redhat.com/errata/RHSA-2016-1001.html http://rhn.redhat.com/errata/RHSA-2016-1002.html http://rhn.redhat.com/errata/RHSA-2016-1019.html http://rhn.redhat.com/errata/RHSA-2016-1943.html http://suppor • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2016-3717 – ImageMagick 7.0.1-0 / 6.9.3-9 - 'ImageTragick ' Multiple Vulnerabilities
https://notcve.org/view.php?id=CVE-2016-3717
The LABEL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to read arbitrary files via a crafted image. El codificador LABEL en ImageMagick en versiones anteriores a 6.9.3-10 y 7.x en versiones anteriores a 7.0.1-1 permite a atacantes remotos leer archivos arbitrarios a través de una imagen manipulada. It was discovered that certain ImageMagick coders and pseudo-protocols did not properly prevent security sensitive operations when processing specially crafted images. A remote attacker could create a specially crafted image that, when processed by an application using ImageMagick or an unsuspecting user using the ImageMagick utilities, would allow the attacker to disclose the contents of arbitrary files. • https://www.exploit-db.com/exploits/39767 http://git.imagemagick.org/repos/ImageMagick/blob/a01518e08c840577cabd7d3ff291a9ba735f7276/ChangeLog http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00051.html http • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2016-3715 – ImageMagick Arbitrary File Deletion Vulnerability
https://notcve.org/view.php?id=CVE-2016-3715
The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image. El codificador EPHEMERAL en ImageMagick en versiones anteriores a 6.9.3-10 y 7.x en versiones anteriores a 7.0.1-1 permite a atacantes remotos eliminar archivos arbitrarios a través de una imagen manipulada. It was discovered that certain ImageMagick coders and pseudo-protocols did not properly prevent security sensitive operations when processing specially crafted images. A remote attacker could create a specially crafted image that, when processed by an application using ImageMagick or an unsuspecting user using the ImageMagick utilities, would allow the attacker to delete arbitrary files. ImageMagick contains an unspecified vulnerability that could allow users to delete files by using ImageMagick's 'ephemeral' pseudo protocol, which deletes files after reading. • https://www.exploit-db.com/exploits/39767 http://git.imagemagick.org/repos/ImageMagick/blob/a01518e08c840577cabd7d3ff291a9ba735f7276/ChangeLog http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00051.html http • CWE-20: Improper Input Validation •
