ubuntu-system-service 0.2.4 before 0.2.4.1. 0.2.3 before 0.2.3.1, and 0.2.2 before 0.2.2.1 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.

systemd 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.

Race condition in PolicyKit (aka polkit) allows local users to bypass intended PolicyKit restrictions and gain privileges by starting a setuid or pkexec process before the authorization check is performed, related to (1) the polkit_unix_process_new API function, (2) the dbus API, or (3) the --process (unix-process) option for authorization to pkcheck.

dbus/SoftwarePropertiesDBus.py in Software Properties 0.92.17 before 0.92.17.3, 0.92.9 before 0.92.9.3, and 0.82.7 before 0.82.7.5 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.

The vino_server_client_data_pending function in vino-server.c in GNOME Vino 2.26.1, 2.32.1, 3.7.3, and earlier, and 3.8 when encryption is disabled, does not properly clear client data when an error causes the connection to close during authentication, which allows remote attackers to cause a denial of service (infinite loop, CPU and disk consumption) via multiple crafted requests during authentication.

OpenStack Identity (Keystone) Folsom, Grizzly 2013.1.3 and earlier, and Havana before havana-3 does not properly revoke user tokens when a tenant is disabled, which allows remote authenticated users to retain access via the token.

The remoteDispatchDomainMemoryStats function in daemon/remote.c in libvirt 0.9.1 through 0.10.1.x, 0.10.2.x before 0.10.2.8, 1.0.x before 1.0.5.6, and 1.1.x before 1.1.2 allows remote authenticated users to cause a denial of service (uninitialized pointer dereference and crash) via a crafted RPC call.

The X509Extension in pyOpenSSL before 0.13.1 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

Use-after-free vulnerability in drivers/net/tun.c in the Linux kernel through 3.11.1 allows local users to gain privileges by leveraging the CAP_NET_ADMIN capability and providing an invalid tuntap interface name in a TUNSETIFF ioctl call.

A certain Ubuntu build procedure for perf, as distributed in the Linux kernel packages in Ubuntu 10.04 LTS, 12.04 LTS, 12.10, 13.04, and 13.10, sets the HOME environment variable to the ~buildd directory and consequently reads the system configuration file from the ~buildd directory, which allows local users to gain privileges by leveraging control over the buildd account.
