Debian Security Advisory DSA 1963-1 (unbound)
Published: 2009-12-30 20:58:43
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P
Recommendations:
https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201963-1
Technical Details:
It was discovered that Unbound, a DNS resolver, does not properly
check cryptographic signatures on NSEC3 records. As a result, zones
signed with the NSEC3 variant of DNSSEC lose their cryptographic
protection. (An attacker would still have to carry out an ordinary
cache poisoning attack to add bad data to the cache.)
The old stable distribution (etch) does not contain an unbound
Linux Distribution Package.
For the stable distribution (lenny), this problem has been fixed in
version 1.0.2-1+lenny1.
For the unstable distribution (sid) and the testing distribution
(squeeze), this problem has been fixed in version 1.3.4-1.
We recommend that you upgrade your unbound Linux Distribution Package.
Summary:
The remote host is missing an update to unbound
announced via advisory DSA 1963-1.
Detection Type:
Linux Distribution Package
Solution Type:
Vendor Patch

What's vulnerability management?
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".
