| <description> |
| <p> |
| The Mandriva Linux Engineering Team has reported a stack-based buffer |
| overflow in the subnet-mask handling of dhclient. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A remote attacker might set up a rogue DHCP server in a victim's local |
| network, possibly leading to the execution of arbitrary code with root |
| privileges. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All ISC DHCP users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-misc/dhcp-3.1.1-r1"</code> |
| </resolution> |
