Technical Details:
Steven van Acker reported on bugtraq that the version of cfingerd (a configurable finger daemon) as distributed in Debian GNU/Linux 2.2 suffers from two problems: 1. The code that reads configuration files (files in which $ commands are expanded) copied its input to a buffer without checking for a buffer overflow. When the ALLOW_LINE_PARSING feature is enabled that code is used for reading users files as well, so local users could exploit this. 2. There also was a printf call in the same routine that did not protect against printf format attacks. Since ALLOW_LINE_PARSING is enabled in the default /etc/cfingerd.conf local users could use this to gain root access. This has been fixed in version 1.4.1-1.2, and we recommend that you upgrade

Summary:
The remote host is missing an update to cfingerd announced via advisory DSA 066-1.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
