| Alvaro Martinez Echevarria discovered a hole in the CUPS Internet Printing |
| Protocol (IPP) implementation that allows remote attackers to cause CUPS to |
| stop listening on the IPP port. |

| </description> |
| <impact type="normal"> |
| <p> |
| A remote user with malicious intent can easily cause a denial of service to |
| the CUPS daemon by sending a specially-crafted UDP datagram packet to the |
| IPP port. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All CUPS users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge sync |
| |
| # emerge -pv ">=net-print/cups-1.1.20-r2" |
| # emerge ">=net-print/cups-1.1.20-r2"</code> |
| </resolution> |
