Medium Nessus Plugin ID 99435

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that the resolver in Bind made incorrect assumptions about ordering when processing responses containing a CNAME or DNAME.
An attacker could use this cause a denial of service. (CVE-2017-3137)

Oleg Gorokhov discovered that in some situations, Bind did not properly handle DNS64 queries. An attacker could use this to cause a denial of service. (CVE-2017-3136)
