Background ========== libvirt is a C toolkit for manipulating virtual machines. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-emulation/libvirt < 1.0.5.1-r3 >= 1.0.5.1-r3 Description =========== An error in the virNetMessageFree() function in rpc/virnetserverclient.c can lead to a use-after-free. Additionally, a socket leak in the remoteDispatchStoragePoolListAllVolumes command can lead to file descriptor exhaustion. Impact ====== A remote attacker could cause certain errors during an RPC connection to cause a message to be freed without being removed from the message queue, possibly resulting in execution of arbitrary code or a Denial of Service condition. Additionally, a remote attacker could repeatedly issue the command to list all pool volumes, causing a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All libvirt users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot -v ">=app-emulation/libvirt-1.0.5.1-r3" References ========== [ 1 ] CVE-2013-0170 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0170 [ 2 ] CVE-2013-1962 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1962 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201309-18.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
