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 installation of ISC BIND running on the remote name server is version 9.10.x prior to 9.11.22, 9.12.x prior to 9.16.6 or 9.17.x prior to 9.17.4. It is, therefore, affected by a denial of service (DoS). If BIND is built with --enable-native-pkcs11 then a specially crafted query for a zone signed with RSA can trigger an assertion failure. An unauthenticated, remote attacker can exploit this issue via a specially crafted query packet to trigger a crash on the server.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to BIND 9.11.22, 9.16.6, 9.17.4 or later.
