More information:

The Internet Software Consortium discovered several vulnerabilities during an audit of the ISC DHCP Daemon. The vulnerabilities exist in error handling routines within the minires library and may be exploitable as stack overflows. This could allow a remote attacker to execute arbitrary code under the user id the dhcpd runs under, usually root. Other DHCP servers than dhcp3 doesn't seem to be affected.

For the stable distribution (woody) this problem has been fixed in version 3.0+3.0.1rc9-2.1.

The old stable distribution (potato) does not contain dhcp3 packages.

For the unstable distribution (sid) this problem has been fixed in version 3.0+3.0.1rc11-1.

We recommend that you upgrade your dhcp3-server package.

Fixed in:
