 Mandriva Linux Security Advisory                         MDVSA-2014:097
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : libvirt
 Date    : May 16, 2014
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been discovered and corrected in libvirt:

 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).

 The updated packages have been upgraded to the 1.1.3.5 version and
 patched to correct these issues.
