NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt package and not the libvirt package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

Use-after-free vulnerability in the virNetMessageFree function in rpc/virnetserverclient.c in libvirt 1.0.x before 1.0.2, 0.10.2 before 0.10.2.3, 0.9.11 before 0.9.11.9, and 0.9.6 before 0.9.6.4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by triggering certain errors during an RPC connection, which causes a message to be freed without being removed from the message queue.
