Mandrake Linux Security Advisory : dhcp (MDKSA-2002:037)

critical Nessus Plugin ID 13942

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

Description

Fermin J. Serna discovered a problem in the dhcp server and client package from versions 3.0 to 3.0.1rc8, which are affected by a format string vulnerability that can be exploited remotely. By default, these versions of DHCP are compiled with the dns update feature enabled, which allows DHCP to update DNS records. The code that logs this update has an exploitable format string vulnerability; the update message can contain data provided by the attacker, such as a hostname.
A successful exploitation could give the attacker elevated privileges equivalent to the user running the DHCP daemon, which is the user dhcpd in Mandrake Linux 8.x, but root in earlier versions.

Solution

Update the affected packages.
