The RPCBind utility is a server that converts RPC program numbers into universal addresses.
A use-after-free vulnerability was discovered in RPCBind’s svc_dodestroy function when trying to free a corrupted xprt->xp_netid pointer.
A remote attacker could possibly cause a Denial of Service condition.
There is no known workaround at this time.
All RPCBind users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-nds/rpcbind-0.2.3-r1"
