Technical Details:
Several vulnerabilities have been discovered in mapserver, a CGI-based web framework to publish spatial data and interactive mapping applications. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-0843 Missing input validation on a user supplied map queryfile name can be used by an attacker to check for the existence of a specific file by using the queryfile GET parameter and checking for differences in error messages. CVE-2009-0842 A lack of file type verification when parsing a map file can lead to partial disclosure of content from arbitrary files through parser error messages. CVE-2009-0841 Due to missing input validation when saving map files under certain conditions it is possible to perform directory traversal attacks and to create arbitrary files. NOTE: Unless the attacker is able to create directories in the image path or there is already a readable directory this doesn't affect installations on Linux as the fopen() syscall will fail in case a sub path is not readable. CVE-2009-0839 It was discovered that mapserver is vulnerable to a stack-based buffer overflow when processing certain GET parameters. An attacker can use this to execute arbitrary code on the server via crafted id parameters. CVE-2009-0840 An integer overflow leading to a heap-based buffer overflow when processing the Content-Length header of an HTTP request can be used by an attacker to execute arbitrary code via crafted POST requests containing negative Content-Length values. CVE-2009-2281 An integer overflow when processing HTTP requests can lead to a heap-based buffer overflow. An attacker can use this to execute arbitrary code either via crafted Content-Length values or large HTTP request. This is partly because of an incomplete fix for CVE-2009-0840. For the oldstable distribution (etch), this problem has been fixed in version 4.10.0-5.1+etch4. For the stable distribution (lenny), this problem has been fixed in version 5.0.3-3+lenny4. For the testing distribution (squeeze), this problem has been fixed in version 5.4.2-1. For the unstable distribution (sid), this problem has been fixed in version 5.4.2-1. We recommend that you upgrade your mapserver Linux Distribution Packages.

Summary:
The remote host is missing an update to mapserver announced via advisory DSA 1914-1.

Frequently Asked Questions

No, you can scan concurrently as many assets as you want. Please note that you must be aware of the hardware requeriments of the platform to ensure a good performance.

No, you can add as many assest as you want. It doesn't matters if you have millions of assets, we won't charge you for that.

No. The software is completely free. We have no intention to charge you to use the software, in fact - it completely goes against our beliefs and business model.

A vulnerability is defined in the ISO 27002 standard as “A weakness of an asset or group of assets that can be exploited by one or more threats” (International Organization for Standardization, 2005)

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".
