libvirt: Multiple vulnerabilities Multiple vulnerabilities have been found in libvirt, allowing remote attackers to execute arbitrary code or cause Denial of Service. libvirt 2013-09-25 2013-09-25 454588 470096 remote

libvirt is a C toolkit for manipulating virtual machines.

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.

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.

There is no known workaround at this time.

All libvirt users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=app-emulation/libvirt-"
