Debian DSA-1833-1 : dhcp3 - several vulnerabilities

critical Nessus Plugin ID 44698

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Several remote vulnerabilities have been discovered in ISC's DHCP implementation :

- 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.

Solution

Upgrade the dhcp3 packages.

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.
