lua: overflow flaw in vararg functions

Buffer overflow in the vararg functions in ldo.c in Lua 5.1 through 5.2.x before 5.2.3 allows context-dependent attackers to cause a denial of service (crash) via a small number of arguments to a function with a large number of fixed arguments.

openssl: client-side denial of service when using anonymous ECDH

The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service (NULL pointer dereference and client crash) by triggering a NULL certificate value.

Use-after-free vulnerability in core/dom/ContainerNode.cpp in the DOM implementation in Blink, as used in Google Chrome before 37.0.2062.94, allows remote attackers to cause a denial of service or possibly have unspecified other impact by leveraging script execution that occurs before notification of node removal.

Unspecified vulnerability in the Oracle VM VirtualBox component in Oracle Virtualization VirtualBox before 4.3.20 allows local users to affect integrity and availability via vectors related to VMSVGA virtual graphics device, a different vulnerability than CVE-2014-6588, CVE-2014-6589, CVE-2014-6595, and CVE-2015-0427.

OpenJDK: class verifier insufficient invokespecial calls verification (Hotspot, 8058982)

Unspecified vulnerability in Oracle Java SE 6u85, 7u72, and 8u25 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Hotspot.

kernel: xen: Race condition in HVMOP_track_dirty_vram (XSA-104)

Race condition in HVMOP_track_dirty_vram in Xen 4.0.0 through 4.4.x does not ensure possession of the guarding lock for dirty video RAM tracking, which allows certain local guest domains to cause a denial of service via unspecified vectors.

IPython Notebook 0.12 through 1.x before 1.2 does not validate the origin of websocket requests, which allows remote attackers to execute arbitrary code by leveraging knowledge of the kernel id and a crafted page.

rubygem-actionpack: incomplete fix for CVE-2014-7818, arbitrary file existence disclosure

Directory traversal vulnerability in actionpack/lib/action_dispatch/middleware/static.rb in Action Pack in Ruby on Rails 3.x before 3.2.21, 4.0.x before 4.0.12, 4.1.x before 4.1.8, and 4.2.x before 4.2.0.beta4, when serve_static_assets is enabled, allows remote attackers to determine the existence of files outside the application root via vectors involving a \ (backslash) character, a similar issue to CVE-2014-7818.

ICU: regexp engine incorrect handling of a zero length quantifier

The Regular Expressions package in International Components for Unicode (ICU) 52 before SVN revision 292944, as used in Google Chrome before 40.0.2214.91, allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via vectors related to a zero-length quantifier.

chromium-browser: same-origin-bypass in V8

Google Chrome before 40.0.2214.91, when the Harmony proxy in Google V8 is enabled, allows remote attackers to bypass the Same Origin Policy via crafted JavaScript code with Proxy.create and console.log calls, related to HTTP responses that lack an "X-Content-Type-Options: nosniff" header.

openstack-horizon: multiple XSS flaws

Cross-site scripting (XSS) vulnerability in the Orchestration/Stack section in the Horizon Orchestration dashboard in OpenStack Dashboard (Horizon) before 2013.2.4, 2014.1 before 2014.1.2, and Juno before Juno-2, when used with Heat, allows remote Orchestration template owners or catalogs to inject arbitrary web script or HTML via a crafted template.

subversion: incorrect SSL certificate validation in Serf RA (repository access) layer

The Serf RA layer in Apache Subversion 1.4.0 through 1.7.x before 1.7.18 and 1.8.x before 1.8.10 does not properly handle wildcards in the Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.

The Dispatch_Write function in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB 1.4.4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers an out-of-bounds write.

OpenVPN 2.x before 2.0.11, 2.1.x, 2.2.x before 2.2.3, and 2.3.x before 2.3.6 allows remote authenticated users to cause a denial of service (server crash) via a small control channel packet.

Multiple integer signedness errors in the Dispatch_Write function in proxy/dispatcher/idirectfbsurface_dispatcher.c in DirectFB 1.4.13 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the Voodoo interface, which triggers a stack-based buffer overflow.

kernel: x86: espfix not working for 32-bit KVM paravirt guests

The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel through 3.18 uses an improper paravirt_enabled setting for KVM guest kernels, which makes it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value.

The default D-Bus access control rule in Midgard2 10.05.7.1 allows local users to send arbitrary method calls or signals to any process on the system bus and possibly execute arbitrary code with root privileges.

Vala: Heap-buffer overflow in vala-gstreamer bindings at Gst.MapInfo()

The Gst.MapInfo function in Vala 0.26.0 and 0.26.1 uses an incorrect buffer length declaration for the Gstreamer bindings, which allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors, which trigger a heap-based buffer overflow.

kernel: iptables restriction bypass if a protocol handler kernel module not loaded

net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with disallowed port numbers.

castor: XML External Entity (XXE) attacks via a crafted XML document

The default configuration for the Xerces SAX Parser in Castor before 1.3.3 allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted XML document.
