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: 4.4
SynopsisThe remote EulerOS Virtualization host is missing a security update.
DescriptionAccording to the version of the bind packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :
- 'deny-answer-aliases' is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers.

Affects BIND 9.7.0-i1/4z9.8.8, 9.9.0-i1/4z9.9.13, 9.10.0-i1/4z9.10.8, 9.11.0-i1/4z9.11.4, 9.12.0-i1/4z9.12.2, 9.13.0-i1/4z9.13.2.(CVE-2018-5740)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
