Synopsis
========
The Network Audio System is vulnerable to a buffer overflow that could
result in the execution of arbitrary code with root privileges.
Background
==========
NAS is a network transparent, client/server audio transport system.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/nas < 1.8b >= 1.8b
Description
===========
Luigi Auriemma has discovered multiple vulnerabilities in NAS, some of
which include a buffer overflow in the function accept_att_local(), an
integer overflow in the function ProcAuWriteElement(), and a null
pointer error in the function ReadRequestFromClient().
Impact
======
An attacker having access to the NAS daemon could send an overly long
slave name to the server, leading to the execution of arbitrary code
with root privileges. A remote attacker could also send a specially
crafted packet containing an invalid client ID, which would crash the
server and result in a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All NAS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/nas-1.8b"
