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 FreeBSD host is missing one or more security-related updates.
DescriptionISC reports :
A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate.
An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were met.
Mistaken assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records could lead to a situation in which named would exit with an assertion failure when processing a response in which records occurred in an unusual order.
named contains a feature which allows operators to issue commands to a running server by communicating with the server process over a control channel, using a utility program such as rndc.
A regression introduced in a recent feature change has created a situation under which some versions of named can be caused to exit with a REQUIRE assertion failure if they are sent a null command string.
