MGASA-2014-0243 - Updated libvirt packages fix multiple vulnerabilities Publication date: 29 May 2014 URL: http://advisories.mageia.org/MGASA-2014-0243.html 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).
