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.

SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionISC reports :
High numbers of queries with DNSSEC validation enabled can cause an assertion failure in named, caused by using a 'bad cache' data structure before it has been initialized.
BIND 9 stores a cache of query names that are known to be failing due to misconfigured name servers or a broken chain of trust. Under high query loads when DNSSEC validation is active, it is possible for a condition to arise in which data from this cache of failing queries could be used before it was fully initialized, triggering an assertion failure.
This bug cannot be encountered unless your server is doing DNSSEC validation.
