The remote host is running Bind, a popular name server.
Versions of BIND 9.6 earlier than 9.6-ESV-R4-P3, 9.7 earlier than 9.7.3-P3, and 9.8 earlier than 9.8.0-P4 are potentially affected by a denial of service vulnerability. If an attacker sends a specially crafted request to a BIND server it may cause the name server process to crash.
