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: 3.6
SynopsisThe remote name server is affected by a denial of service vulnerability.
DescriptionAccording to its self-reported version number, the remote Unbound DNS resolver is affected by a denial of service vulnerability in the Domain Name Service due to improper handling of a maliciously-constructed zone or queries from a rogue server. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to cause the service to issue unlimited queries in an attempt to follow a delegation, resulting in a denial of service condition.
SolutionUpgrade to Unbound version 1.5.1 or later. Alternatively, apply the patch provided by the vendor.
