Insight

Insight

Megyer Laszlo report on Bugtraq that the cfingerd Debian as distributed with Debian GNU/Linux 2.2 was not careful in its logging code. By combining this with an off-by-one error in the code that copied the username from an ident response cfingerd could exploited by a remote user. Since cfingerd does not drop its root privileges until after it has determined which user to finger an attacker can gain root privileges. This has been fixed in version 1.4.1-1.1, and we recommend that you upgrade your cfingerd package immediately.
