Cisco Security Advisory – A vulnerability in the DNS code of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to cause an affected system to reload. The vulnerability is due to improper processing of DNS packets. An attacker could exploit this vulnerability by sending a request to an affected Cisco ASA appliance to cause it to generate a DNS request packet. The attacker would need to spoof the reply packet with a crafted DNS response.

Cisco Security Advisory – A vulnerability in the Internet Key Exchange (IKE) version 1 (v1) code of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to cause an affected system to reload. The vulnerability is due to improper handling of Internet Security Association and Key Management Protocol (ISAKMP) packets. An attacker could exploit this vulnerability by sending crafted UDP packets to the affected system. A successful exploit could allow the attacker to cause an affected system to reload.

Red Hat Security Advisory 2015-1919-01 – The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit. Multiple flaws were discovered in the CORBA, Libraries, RMI, Serialization, and 2D components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions. Multiple denial of service flaws were found in the JAXP component in OpenJDK. A specially crafted XML file could cause a Java application using JAXP to consume an excessive amount of CPU and memory when parsed.

Red Hat Security Advisory 2015-1923-01 – KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM. A heap buffer overflow flaw was found in the way QEMU’s NE2000 NIC emulation implementation handled certain packets received over the network. A privileged user inside a guest could use this flaw to crash the QEMU instance or potentially execute arbitrary code on the host.

Ubuntu Security Notice 2770-2 – USN-2770-1 fixed vulnerabilities in Oxide in Ubuntu 14.04 LTS and Ubuntu 15.04. This update provides the corresponding updates for Ubuntu 15.10. It was discovered that ContainerNode::parserInsertBefore in Blink would incorrectly proceed with a DOM tree insertion in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. A use-after-free was discovered in the service worker implementation in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking the program. Various other issues were also addressed.
