CVE-2013-0170

MEDIUM 6.8EPSS 5.77%

Does this matter?

Lower severity and a low EPSS score (5.77%). Track it; it rarely justifies an emergency change on its own.

Description

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.
