(Plone): Partial denial of service through Collections functionality

queryCatalog.py in Plone before 4.2.3 and 4.3 before beta 1 allows remote attackers to bypass caching and cause a denial of service via a crafted request to a collection.

Qemu: 9pfs: memory leakage via proxy/handle callbacks

Memory leak in hw/9pfs/9p-proxy.c in QEMU (aka Quick Emulator) allows local privileged guest OS users to cause a denial of service (host memory consumption and possibly QEMU process crash) by leveraging a missing cleanup operation in the proxy backend.

Mozilla: onbeforeunload and Javascript navigation DOS (MFSA 2014-20)

Mozilla Firefox before 28.0 and SeaMonkey before 2.25 allow remote attackers to cause a denial of service (resource consumption and application hang) via onbeforeunload events that trigger background JavaScript execution.

openstack-nova: Nova VMware driver leaks rescued images

The VMWare driver in OpenStack Compute (Nova) 2013.2 through 2013.2.2 does not properly put VMs into RESCUE status, which allows remote authenticated users to bypass the quota limit and cause a denial of service (resource consumption) by requesting the VM be put into rescue and then deleting the image.

Kernel: mm: try_to_unmap_cluster() should lock_page() before mlocking

The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings.

The Intercluster Sync Agent Service in Cisco Unified Presence Server allows remote attackers to cause a denial of service via a TCP SYN flood, aka Bug ID CSCun34125.

openstack-nova: incomplete fix for CVE-2014-2573, Nova VMware driver still leaks rescued images

The VMWare driver in OpenStack Compute (Nova) before 2014.1.3 allows remote authenticated users to bypass the quota limit and cause a denial of service (resource consumption) by putting the VM into the rescue state, suspending it, which puts into an ERROR state, and then deleting the image. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2573.

dbus: denial of service by creating unkillable D-Bus connections

D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 does not properly close connections for processes that have terminated, which allows local users to cause a denial of service via a D-bus message containing a D-Bus connection file descriptor.

dbus: denial of service in method call handling

The bus_connections_check_reply function in config-parser.c in D-Bus before 1.6.24 and 1.8.x before 1.8.8 allows local users to cause a denial of service (CPU consumption) via a large number of method calls.

dbus: denial of service flaw in incomplete connection handling

The dbus-daemon in D-Bus before 1.6.24 and 1.8.x before 1.8.8 does not properly close old connections, which allows local users to cause a denial of service (incomplete connection consumption and prevention of new connections) via a large number of incomplete connections.

libarchive: Memory leak in TAR parser

Memory leak in the __archive_read_get_extract function in archive_read_extract2.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service via a tar file.

openstack-nova: May fail to delete images in resize state regression

OpenStack Compute (nova) 13.0.0 does not properly delete instances from compute nodes, which allows remote authenticated users to cause a denial of service (disk consumption) by deleting instances while in the resize state. NOTE: this vulnerability exists because of a CVE-2015-3280 regression.

libxml2: denial of service via recursive entity expansion

parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack.

jenkins: denial of service (SECURITY-87)

Jenkins before 1.583 and LTS before 1.565.3 allows remote attackers to cause a denial of service (thread consumption) via vectors related to a CLI handshake.

xen: Unrestricted qemu logging

The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr.

kernel: net: sctp: fix panic on duplicate ASCONF chunks

The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that trigger an incorrect uncork within the side-effect interpreter.

kernel: kvm: vmx: invalid host cr4 handling across vm entries

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU.

openstack-nova: Nova network denial of service through API filtering

OpenStack Compute (Nova) before 2014.1.4 and 2014.2.x before 2014.2.1 allows remote authenticated users to cause a denial of service (CPU consumption) via an IP filter in a list active servers API request.

Katello: user parameters passed to to_sym

Katello allows remote attackers to cause a denial of service (memory consumption) via the (1) mode parameter in the setup_utils function in content_search_controller.rb or (2) action parameter in the respond function in api/api_controller.rb in app/controllers/katello/, which is passed to the to_sym method.

openstack-glance: Glance store disk space exhaustion

OpenStack Image Registry and Delivery Service (Glance) before 2013.2.4, 2014.x before 2014.1.3, and Juno before Juno-3, when using the V2 API, does not properly enforce the image_size_cap configuration option, which allows remote authenticated users to cause a denial of service (disk consumption) by uploading a large image.
