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.

Synopsis
The remote Gentoo host is missing one or more security-related patches.
Description
The remote host is affected by the vulnerability described in GLSA-201006-11 (BIND: Multiple vulnerabilities)
Multiple cache poisoning vulnerabilities were discovered in BIND. For further information please consult the CVE entries and the ISC Security Bulletin referenced below.
Note: CVE-2010-0290 and CVE-2010-0382 exist because of an incomplete fix and a regression for CVE-2009-4022.
Impact :
An attacker could exploit this weakness to poison the cache of a recursive resolver and thus spoof DNS traffic, which could e.g. lead to the redirection of web or mail traffic to malicious sites.
Workaround :
There is no known workaround at this time.
Solution
All BIND users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/bind-9.4.3_p5'
