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

Synopsis

The remote name server is affected by a denial of service vulnerability.

Description

The version of ISC BIND installed on the remote host is affected by a denial of service (DoS) vulnerability in rbtdb.c due to an assertion failure. An authenticated, remote attacker can exploit this issue, to cause a DoS condition.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version

Solution

Upgrade to ISC BIND version 9.11.19-S9 / 9.11.20 / 9.14.13 / 9.16.4 or later
