xen: libxl partially sets up HVM passthrough even with disabled iommu

The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction.

Light Display Manager (aka LightDM) 1.4.x before 1.4.3, 1.6.x before 1.6.2, and 1.7.x before 1.7.14 uses 0664 permissions for the temporary .Xauthority file, which allows local users to obtain sensitive information by reading the file.

wp-admin/includes/post.php in WordPress before 3.6.1 allows remote authenticated users to spoof the authorship of a post by leveraging the Author role and providing a modified user_ID parameter.

xinetd: ignores user and group directives for tcpmux services

xinetd does not enforce the user and group configuration directives for TCPMUX services, which causes these services to be run as root and makes it easier for remote attackers to gain privileges by leveraging another vulnerability in a service.

Kernel: Xen: Xsa-64: memory leak by 64bit PV guests under live migration

Xen 4.3.x writes hypervisor mappings to certain shadow pagetables when live migration is performed on hosts with more than 5TB of RAM, which allows local 64-bit PV guests to read or write to invalid memory and cause a denial of service (crash).

WEB-DAV Linux File System (davfs2) 1.4.6 and 1.4.7 allow local users to gain privileges via unknown attack vectors in (1) kernel_interface.c and (2) mount_davfs.c, related to the "system" function.

The Make Meeting Scheduler module 6.x-1.x before 6.x-1.3 for Drupal allows remote attackers to bypass intended access restrictions for a poll via a direct request to the node's URL instead of the hashed URL.

libvirt: virt-login-shell arbitrary file overwrites vulnerability

virt-login-shell in libvirt 1.1.2 through 1.1.3 allows local users to overwrite arbitrary files and possibly gain privileges via unspecified environment variables or command-line arguments.

libvirt: unintended API access due to incorrect permissions checks

The virConnectDomainXMLToNative API function in libvirt 1.1.0 through 1.1.3 checks for the connect:read permission instead of the connect:write permission, which allows attackers to gain domain:write privileges and execute Qemu binaries via crafted XML. NOTE: some of these details are obtained from third party information.

cumin: missing authorization checks in forms, charts, and csv export widgets

cumin in Red Hat Enterprise MRG Grid 2.4 does not properly enforce user roles, which allows remote authenticated users to bypass intended role restrictions and obtain sensitive information or perform privileged operations via unspecified vectors.

The modbus_125_handler function in the Schneider Electric Quantum Ethernet Module on the NOE 771 device (aka the Quantum 140NOE771* module) allows remote attackers to install arbitrary firmware updates via a MODBUS 125 function code to TCP port 502.

libguestfs: insecure temporary directory handling for guestfish's network socket

The guestfish command in libguestfs 1.20.12, 1.22.7, and earlier, when using the --remote or --listen option, does not properly check the ownership of /tmp/.guestfish-$UID/ when creating a temporary socket file in this directory, which allows local users to write to the socket and execute arbitrary commands by creating /tmp/.guestfish-$UID/ in advance.

Glance: image_download policy not enforced for cached images

OpenStack Image Registry and Delivery Service (Glance) Folsom, Grizzly before 2013.1.4, and Havana before 2013.2, when the download_image policy is configured, does not properly restrict access to cached images, which allows remote authenticated users to read otherwise restricted images via an image UUID.

The nsDocument::MaybePreLoadImage function in content/base/src/nsDocument.cpp in the image-preloading implementation in Mozilla Firefox 3.6 before 3.6.2 does not apply scheme restrictions and policy restrictions to the image's URL, which might allow remote attackers to cause a denial of service (application crash or hang) or hijack the functionality of the browser's add-ons via a crafted SRC attribute of an IMG element, as demonstrated by remote command execution through an ssh: URL in a configuration that supports gnome-vfs with a nonstandard network.gnomevfs.supported-protocols setting.

The GetInstalledPackages function in the configuration tool in HP Application Lifestyle Management (ALM) 11 on AIX, HP-UX, and Solaris allows local users to gain privileges via (1) a Trojan horse /tmp/tmp.txt FIFO or (2) a symlink attack on /tmp/tmp.txt.

Smarty before 3.0.0, when security is enabled, does not prevent access to the (1) dynamic and (2) private object members of an assigned object, which has unspecified impact and remote attack vectors.

Salt (aka SaltStack) before 0.15.0 through 0.17.0 allows remote authenticated minions to impersonate arbitrary minions via a crafted minion with a valid key.

The json rendering functionality in the Context module 6.x-2.x before 6.x-3.2 and 7.x-3.x before 7.x-3.0 for Drupal uses Drupal's token scheme to restrict access to blocks, which makes it easier for remote authenticated users to guess the access token for a block by leveraging the token from a block to which the user has access.

Ruckus Wireless Zoneflex 2942 devices with firmware 9.6.0.0.267 allow remote attackers to bypass authentication, and subsequently access certain configuration/ and maintenance/ scripts, by constructing a crafted URI after receiving an authentication error for an arbitrary login attempt.

hxds.dll in Microsoft Office 2007 SP3 and 2010 SP1 and SP2 does not implement the ASLR protection mechanism, which makes it easier for remote attackers to execute arbitrary code via a crafted COM component on a web site that is visited with Internet Explorer, as exploited in the wild in December 2013, aka "HXDS ASLR Vulnerability."
