CVE-2009-0692

It was discovered that dhclient does not properly handle overlong subnet mask options, leading to a stack-based buffer overflow and possible arbitrary code execution.

CVE-2009-1892

Christoph Biedl discovered that the DHCP server may terminate when receiving certain well-formed DHCP requests, provided that the server configuration mixes host definitions using 'dhcp-client-identifier' and 'hardware ethernet'. This vulnerability only affects the lenny versions of dhcp3-server and dhcp3-server-ldap.

For the old stable distribution (etch), these problems have been fixed in version 3.0.4-13+etch2.

For the stable distribution (lenny), this problem has been fixed in version 3.1.1-6+lenny2.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your dhcp3 packages.");
