CVE-2017-2634 – kernel: dccp: crash while sending ipv6 reset packet
https://notcve.org/view.php?id=CVE-2017-2634
It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation before 2.6.22.17 used the IPv4-only inet_sk_rebuild_header() function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system. Se ha encontrado que la implementación del Protocolo de Control de Congestión de Datagramas (DCCP) del kernel de Linux en versiones anteriores a la 2.6.22.17 usaba la función inet_sk_rebuild_header() solo para IPv4 y conexiones DCCP IPv6, lo que podría resultar en corrupciones de memoria. Un atacante remoto podría utilizar este fallo para provocar un cierre inesperado del sistema.

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') •
CVE-2016-3427 – Oracle Java SE and JRockit Unspecified Vulnerability
https://notcve.org/view.php?id=CVE-2016-3427
Unspecified vulnerability in Oracle Java SE 6u113, 7u99, and 8u77; Java SE Embedded 8u77; and JRockit R28.3.9 allows remote attackers to affect confidentiality, integrity, and availability via vectors related to JMX. Vulnerabilidad no especificada en Oracle Java SE 6u113, 7u99 y 8u77; Java SE Embedded 8u77; y JRockit R28.3.9 permite a atacantes remotos afectar a la confidencialidad, integridad y disponibilidad a través de vectores relacionados con JMX. It was discovered that the RMI server implementation in the JMX component in OpenJDK did not restrict which classes can be deserialized when deserializing authentication credentials. A remote, unauthenticated attacker able to connect to a JMX port could possibly use this flaw to trigger deserialization flaws. Oracle Java SE and JRockit contains an unspecified vulnerability that allows remote attackers to affect confidentiality, integrity, and availability via vectors related to Java Management Extensions (JMX). • http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2016-05 • CWE-284: Improper Access Control •
CVE-2015-8126 – libpng: Buffer overflow vulnerabilities in png_get_PLTE/png_set_PLTE functions
https://notcve.org/view.php?id=CVE-2015-8126
Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image. Múltiples desbordamientos de buffer en las funciones (1) png_set_PLTE y (2) png_get_PLTE en libpng en versiones anteriores a 1.0.64, 1.1.x y 1.2.x en versiones anteriores a 1.2.54, 1.3.x y 1.4.x en versiones anteriores a 1.4.17, 1.5.x en versiones anteriores a 1.5.24 y 1.6.x en versiones anteriores a 1.6.19 permiten a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente tener otro impacto no especificado a través de un valor bit-depth pequeño en un fragmento IHDR (también conocido como image header) en una imagen PNG. It was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer overflow or out-of-bounds reads. An attacker could exploit this to cause a crash or potentially execute arbitrary code by tricking an unsuspecting user into processing a specially crafted PNG image. • http://googlechromereleases.blogspot.com/2016/03/stable-channel-update.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172324.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172620.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172647.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172663.html http://lists.fedoraproject.org/pipermail • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
