Technical Details:
Multiple vulnerabilities were discovered in the Common Unix Printing System (CUPS). Several of these issues represent the potential for a remote compromise or denial of service. The Common Vulnerabilities and Exposures project identifies the following problems: . CVE-2002-1383: Multiple integer overflows allow a remote attacker to execute arbitrary code via the CUPSd HTTP interface and the image handling code in CUPS filters. . CVE-2002-1366: Race conditions in connection with /etc/cups/certs/ allow local users with lp privileges to create or overwrite arbitrary files. This is not present in the potato version. . CVE-2002-1367: This vulnerabilities allows a remote attacker to add printers without authentication via a certain UDP packet, which can then be used to perform unauthorized activities such as stealing the local root certificate for the administration server via a 'need authorization' page. . CVE-2002-1368: Negative lengths fed into memcpy() can cause a denial of service and possibly execute arbitrary code. . CVE-2002-1369: An unsafe strncat() function call processing the options string allows a remote attacker to execute arbitrary code via a buffer overflow. . CVE-2002-1371: Zero width images allows a remote attacker to execute arbitrary code via modified chunk headers. . CVE-2002-1372: CUPS does not properly check the return values of various file and socket operations, which could allow a remote attacker to cause a denial of service. . CVE-2002-1384: The cupsys Linux Distribution Package contains some code from the xpdf Linux Distribution Package, used to convert PDF files for printing, which contains an exploitable integer overflow bug. This is not present in the potato version. Even though we tried very hard to fix all problems in the Linux Distribution Packages for potato as well, the Linux Distribution Packages may still contain other security related problems. Hence, we advise users of potato systems using CUPS to upgrade to woody soon. For the current stable distribution (woody), these problems have been fixed in version 1.1.14-4.3. For the old stable distribution (potato), these problems have been fixed in version 1.0.4-12.1. For the unstable distribution (sid), these problems have been fixed in version 1.1.18-1. We recommend that you upgrade your CUPS Linux Distribution Packages immediately.

The remote host is missing an update to cupsys announced via advisory DSA 232-1.

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".
