Synopsis
========

A buffer overflow in RPCBind might allow remote attackers to cause a
Denial of Service.

Background
==========

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

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-nds/rpcbind < 0.2.3-r1 >= 0.2.3-r1

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.

Resolution
==========

All RPCBind users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-nds/rpcbind-0.2.3-r1"

References
==========
