Linux Distros Unpatched Vulnerability : CVE-2013-6456

medium Nessus Plugin ID 218064

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - The LXC driver (lxc/lxc_driver.c) in libvirt 1.0.1 through 1.2.1 allows local users to (1) delete arbitrary host devices via the virDomainDeviceDettach API and a symlink attack on /dev in the container;
 (2) create arbitrary nodes (mknod) via the virDomainDeviceAttach API and a symlink attack on /dev in the container; and cause a denial of service (shutdown or reboot host OS) via the (3) virDomainShutdown or (4) virDomainReboot API and a symlink attack on /dev/initctl in the container, related to paths under /proc/$PID/root and the virInitctlSetRunLevel function. (CVE-2013-6456)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
