Denial of Service.

Background

The RPCBind utility is a server that converts RPC program numbers into
universal addresses.

Affected packages

Description
==========
A use-after-free vulnerability was discovered in RPCBind's
svc_dodestroy function when trying to free a corrupted xprt->xp_netid
pointer.

Impact

A remote attacker could possibly cause a Denial of Service condition.

Workaround
=========
There is no known workaround at this time.
