Multiple vulnerabilities have been found in libvirt, allowing remote attackers to execute arbitrary code or cause Denial of Service.

2.  Impact Information


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.

3.  Resolution Information


There is no known workaround at this time.


All libvirt users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
  # emerge --ask --oneshot --verbose
