CVE-2017-2620 – Qemu: display: cirrus: potential arbitrary code execution via cirrus_bitblt_cputovideo
https://notcve.org/view.php?id=CVE-2017-2620
Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. Quick emulator (QEMU) en versiones anteriores a la 2.8 construido con el soporte del emulador Cirrus CLGD 54xx VGA Emulator es vulnerable a un problema de acceso fuera de límites. El problema puede ocurrir al copiar datos VGA en cirrus_bitblt_cputovideo. • http://rhn.redhat.com/errata/RHSA-2017-0328.html http://rhn.redhat.com/errata/RHSA-2017-0329.html http://rhn.redhat.com/errata/RHSA-2017-0330.html http://rhn.redhat.com/errata/RHSA-2017-0331.html http://rhn.redhat.com/errata/RHSA-2017-0332.html http://rhn.redhat.com/errata/RHSA-2017-0333.html http://rhn.redhat.com/errata/RHSA-2017-0334.html http://rhn.redhat.com/errata/RHSA-2017-0350.html http://rhn.redhat.com/errata/RHSA-2017-0351.html http://rhn • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVE-2017-2615 – Qemu: display: cirrus: oob access while doing bitblt copy backward mode

CVE-2016-10165 – lcms2: Out-of-bounds read in Type_MLU_Read()
https://notcve.org/view.php?id=CVE-2016-10165
The Type_MLU_Read function in cmstypes.c in Little CMS (aka lcms2) allows remote attackers to obtain sensitive information or cause a denial of service via an image with a crafted ICC profile, which triggers an out-of-bounds heap read. La función Type_MLU_Read en cmstypes.c en Little CMS (también conocido como lcms2) permite a atacantes remotos obtener información sensible o provocar una denegación de servicio a través de una imagen con un perfil ICC manipulado, lo que desencadena una lectura de memoria dinámica fuera de límites. • http://lists.opensuse.org/opensuse-updates/2017-01/msg00174.html http://rhn.redhat.com/errata/RHSA-2016-2079.html http://rhn.redhat.com/errata/RHSA-2016-2658.html http://www.debian.org/security/2017/dsa-3774 http://www.openwall.com/lists/oss-security/2017/01/23/1 http://www.openwall.com/lists/oss-security/2017/01/25/14 http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html http://www.securityfocus.com/bid/95808 http://www.securitytracker.com/id& • CWE-125: Out-of-bounds Read •
CVE-2016-8864 – bind: assertion failure while handling responses containing a DNAME answer
https://notcve.org/view.php?id=CVE-2016-8864
named in ISC BIND 9.x before 9.9.9-P4, 9.10.x before 9.10.4-P4, and 9.11.x before 9.11.0-P1 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a DNAME record in the answer section of a response to a recursive query, related to db.c and resolver.c. named en ISC BIND 9.x en versiones anteriores a 9.9.9-P4, 9.10.x en versiones anteriores a 9.10.4-P4 y 9.11.x en versiones anteriores a 9.11.0-P1 permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de un registro DNAME en la sección de respuesta de una respuesta a una petición recursiva, relacionado con db.c y resolver.c. A denial of service flaw was found in the way BIND handled responses containing a DNAME answer. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response. • http://rhn.redhat.com/errata/RHSA-2016-2141.html http://rhn.redhat.com/errata/RHSA-2016-2142.html http://rhn.redhat.com/errata/RHSA-2016-2615.html http://rhn.redhat.com/errata/RHSA-2016-2871.html http://www.debian.org/security/2016/dsa-3703 http://www.securityfocus.com/bid/94067 http://www.securitytracker.com/id/1037156 https://access.redhat.com/errata/RHSA-2017:1583 https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05381687 https: • CWE-617: Reachable Assertion •
CVE-2016-5195 – Linux Kernel Race Condition Vulnerability
https://notcve.org/view.php?id=CVE-2016-5195
Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the wild in October 2016, aka "Dirty COW." La condición de carrera en mm / gup.c en el kernel de Linux 2.x a 4.x antes de 4.8.3 permite a los usuarios locales obtener privilegios aprovechando el manejo incorrecto de una función copy-on-write (COW) para escribir en un read- only la cartografía de la memoria, como explotados en la naturaleza en octubre de 2016, vulnerabilidad también conocida como "Dirty COW". A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. Race condition in mm/gup.c in the Linux kernel allows local users to escalate privileges. • https://github.com/dirtycow/dirtycow.github.io https://www.exploit-db.com/exploits/40611 https://www.exploit-db.com/exploits/40838 https://www.exploit-db.com/exploits/40616 https://www.exploit-db.com/exploits/40839 https://www.exploit-db.com/exploits/40847 https://github.com/timwr/CVE-2016-5195 https://github.com/gbonacini/CVE-2016-5195 https://github.com/whu-enjoy/CVE-2016-5195 https://github.com/jas502n/CVE-2016-5195 https://github.com/arttnba3/CVE-2016- • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
