https://notcve.org/view.php?id=CVE-2016-6888
Integer overflow in the net_tx_pkt_init function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (QEMU process crash) via the maximum fragmentation count, which triggers an unchecked multiplication and NULL pointer dereference. Desbordamiento de entero en la función net_tx_pkt_enit en hw/net/net_tx_pkt.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (caída del proceso QEMU) a través del conteo máximo de fragmentación, lo que desencadena una multiplicación no comprobada y referencia a un puntero NULL. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=47882fa4975bf0b58dd74474329fdd7154e8f04c http://www.openwall.com/lists/oss-security/2016/08/19/10 http://www.openwall.com/lists/oss-security/2016/08/19/6 http://www.securityfocus.com/bid/92556 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-08/msg03176.html https • CWE-190: Integer Overflow or Wraparound CWE-476: NULL Pointer Dereference •

The virtqueue_map_desc function in hw/virtio/virtio.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via a large I/O descriptor buffer length value. La función virtqueue_map_desc en hw/virtio/virtio.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (referencia a puntero NULL y caída del proceso QEMU) a través de un gran valor de longitud de búfer descriptor de I/O. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=973e7170dddefb491a48df5cba33b2ae151013a0 http://lists.opensuse.org/opensuse-updates/2016-12/msg00140.html http://www.openwall.com/lists/oss-security/2016/09/16/10 http://www.openwall.com/lists/oss-security/2016/09/16/4 http://www.securityfocus.com/bid/92996 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg03546.html https:&# • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2016-4020
The patch_instruction function in hw/i386/kvmvapic.c in QEMU does not initialize the imm32 variable, which allows local guest OS administrators to obtain sensitive information from host stack memory by accessing the Task Priority Register (TPR). La función patch_instruction en hw/i386/kvmvapic.c en QEMU no inicializa la variable imm32, lo que permite a administradores locales del SO invitado obtener información sensible de la memoria de pila del anfitrión accediendo al Task Priority Register (TPR). An information-exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR) optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user inside a guest could use this issue to read portions of the host memory. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=691a02e2ce0c413236a78dee6f2651c937b09fb0 http://www.securityfocus.com/bid/86067 http://www.ubuntu.com/usn/USN-2974-1 https://access.redhat.com/errata/RHSA-2017:1856 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://bugzilla.redhat.com/show_bug.cgi?id=1313686 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 5.8EPSS: 81%CPEs: 84EXPL: 2CVE-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 •

The (1) HTTP and (2) FTP coders in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allow remote attackers to conduct server-side request forgery (SSRF) attacks via a crafted image. Los codificadores (1) HTTP y (2) FTP en ImageMagick en versiones anteriores a 6.9.3-10 y 7.x en versiones anteriores a 7.0.1-1 permiten a atacantes remotos llevar a cabo ataques de falsificación de peticiones del lado del servidor (SSRF) a través de una imagen manipulada. A server-side request forgery flaw was discovered in the way ImageMagick processed certain images. A remote attacker could exploit this flaw to mislead an application using ImageMagick or an unsuspecting user using the ImageMagick utilities into, for example, performing HTTP(S) requests or opening FTP sessions via specially crafted images. ImageMagick contains an unspecified vulnerability that allows attackers to perform server-side request forgery (SSRF) via a crafted image. • 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-352: Cross-Site Request Forgery (CSRF) CWE-918: Server-Side Request Forgery (SSRF) •
