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: 8.8EPSS: 0%CPEs: 47EXPL: 0CVE-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 •
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.

https://notcve.org/view.php?id=CVE-2016-2107
The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169. La implementación de AES-NI en OpenSSL en versiones anteriores a 1.0.1t y 1.0.2 en versiones anteriores a 1.0.2h no considera la asignación de memoria durante una comprobación de relleno determinada, lo que permite a atacantes remotos obtener información de texto claro sensible a través de un ataque de padding-oracle contra una sesión AES CBC . NOTA: esta vulnerabilidad existe debido a una corrección incorrecta para CVE-2013-0169. It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. • https://www.exploit-db.com/exploits/39768 https://github.com/FiloSottile/CVE-2016-2107 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183457.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183607.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184605.html http://lists.opensuse.org/opensuse-security • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-310: Cryptographic Issues •
