spice-gtk: Insecure calling of polkit via polkit_unix_process_new()

spice-gtk 0.14, and possibly other versions, invokes the polkit authority using the insecure polkit_unix_process_new API function, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.

hplip: Insecure calling of polkit

The check_permission_v1 function in base/pkit.py in HP Linux Imaging and Printing (HPLIP) through 3.13.9 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process.

rtkit: insecure calling of polkit

RealtimeKit (aka rtkit) 0.5 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.

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.

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.

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.

ON: World readable configuration files expose sensitive data

Red Hat JBoss Operations Network 3.1.2 uses world-readable permissions for the (1) server and (2) agent configuration files, which allows local users to obtain authentication credentials and other unspecified sensitive information by reading these files.

LightDM 1.7.5 through 1.8.3 and 1.9.x before 1.9.2 does not apply the AppArmor profile to the Guest account, which allows local users to bypass intended restrictions by leveraging the Guest account.

Kernel: net: memory corruption with UDP_CORK and UFO

The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly initialize certain data structures, which allows local users to cause a denial of service (memory corruption and system crash) or possibly gain privileges via a crafted application that uses the UDP_CORK option in a setsockopt system call and sends both short and long packets, related to the ip_ufo_append_data function in net/ipv4/ip_output.c and the ip6_ufo_append_data function in net/ipv6/ip6_output.c.
