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: 5.2


The remote FreeBSD host is missing one or more security-related updates.


Problem description :

The named(8) server does not properly handle DNS resource records where the RDATA field is zero length, which may cause various issues for the servers handling them.

Resolving servers may crash or disclose some portion of memory to the client. Authoritative servers may crash on restart after transferring a zone containing records with zero-length RDATA fields. These would result in a denial of service, or leak of sensitive information.


Update the affected packages.
