New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 4.2
SynopsisThe remote Debian host is missing a security-related update.
DescriptionIt 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.)
SolutionUpgrade the unbound package.
The old stable distribution (etch) does not contain an unbound package.
For the stable distribution (lenny), this problem has been fixed in version 1.0.2-1+lenny1.
