CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Technical Details:
Multiple vulnerabilities have been discovered in devscripts, a set of scripts to make the life of a Debian Package maintainer easier. The following Common Vulnerabilities and Exposures project ids have been assigned to identify them: CVE-2012-2240: Raphael Geissert discovered that dscverify does not perform sufficient validation and does not properly escape arguments to external commands, allowing a remote attacker (as when dscverify is used by dget) to execute arbitrary code. CVE-2012-2241: Raphael Geissert discovered that dget allows an attacker to delete arbitrary files when processing a specially-crafted .dsc or .changes file, due to insuficient input validation. CVE-2012-2242: Raphael Geissert discovered that dget does not properly escape arguments to external commands when processing .dsc and .changes files, allowing an attacker to execute arbitrary code. This issue is limited with the fix for CVE-2012-2241, and had already been fixed in version 2.10.73 due to changes to the code, without considering its security implications. CVE-2012-3500: Jim Meyering, Red Hat, discovered that annotate-output determines the name of temporary named pipes in a way that allows a local attacker to make it abort, leading to denial of service. Additionally, a regression in the exit code of debdiff introduced in DSA-2409-1 has been fixed. For the stable distribution (squeeze), these problems have been fixed in version 2.10.69+squeeze4. For the testing distribution (wheezy), these problems will be fixed soon. For the unstable distribution (sid), these problems will be fixed in version 2.12.3.

Recommendations:
We recommend that you upgrade your devscripts Linux Distribution Packages.

Summary:
The remote host is missing an update to devscripts announced via advisory DSA 2549-1.

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".
