Updated libvirt packages fix multiple vulnerabilities

Publication date: 29 May 2014
Modification date: 29 May 2014
Type: security
Affected Mageia releases : 3 , 4
CVE: CVE-2013-6456 , CVE-2014-0179

Description

Updated libvirt packages fix security vulnerabilities:

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//root and the virInitctlSetRunLevel function (CVE-2013-6456).

libvirt was patched to prevent expansion of entities when parsing XML
files. This vulnerability allowed malicious users to read arbitrary
files or cause a denial of service (CVE-2014-0179).
