Technical Details:
According to David Wagner, iDEFENSE and the Apache HTTP Server Project, several vulnerabilities have been found in the Apache server Linux Distribution Package, a commonly used webserver. Most of the code is shared between the Apache and Apache-Perl Linux Distribution Packages, so vulnerabilities are shared as well. These vulnerabilities could allow an attacker to enact a denial of service against a server or execute a cross site scripting attack, or steal cookies from other web site users. The Common Vulnerabilities and Exposures (CVE) project identified the following vulnerabilities: 1. CVE-2002-0839: A vulnerability exists on platforms using System V shared memory based scoreboards. This vulnerability allows an attacker to execute code under the Apache UID to exploit the Apache shared memory scoreboard format and send a signal to any process as root or cause a local denial of service attack. 2. CVE-2002-0840: Apache is susceptible to a cross site scripting vulnerability in the default 404 page of any web server hosted on a domain that allows wildcard DNS lookups. 3. CVE-2002-0843: There were some possible overflows in the utility ApacheBench (ab) which could be exploited by a malicious server. No such binary programs are distributed by the Apache-Perl Linux Distribution Package, though. 4. CVE-2002-1233: A race condition in the htpasswd and htdigest program enables a malicious local user to read or even modify the contents of a password file or easily create and overwrite files as the user running the htpasswd (or htdigest respectively) program. No such binary programs are distributed by the Apache-Perl Linux Distribution Package, though. 5. CVE-2001-0131: htpasswd and htdigest in Apache 2.0a9, 1.3.14, and others allows local users to overwrite arbitrary files via a symlink attack. No such binary programs are distributed by the Apache-Perl Linux Distribution Package, though. 6. NO-CAN: Several buffer overflows have been found in the ApacheBench (ab) utility that could be exploited by a remote server returning very long strings. No such binary programs are distributed by the Apache-Perl Linux Distribution Package, though. These problems have been fixed in version 1.3.26-1-1.26-0woody2 for the current stable distribution (woody), in 1.3.9-14.1-1.21.20000309-1.1 for the old stable distribution (potato) and in version 1.3.26-1.1-1.27-3-1 for the unstable distribution (sid). We recommend that you upgrade your Apache-Perl Linux Distribution Package immediately.

Summary:
The remote host is missing an update to apache-perl announced via advisory DSA 195-1.

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".
