| <title>NAS: Multiple vulnerabilities</title> |
| <synopsis> |
| The Network Audio System is vulnerable to a buffer overflow that could |
| result in the execution of arbitrary code with root privileges. |

| <background> |
| <p> |
| NAS is a network transparent, client/server audio transport system. |

| <description> |
| <p> |
| 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(). |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| 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. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All NAS users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=media-libs/nas-1.8b"</code> |
| </resolution> |
