FreeBSD : BIND -- multiple vulnerabilities (c6861494-1ffb-11e7-934d-d05099c0ae8c)
Medium Nessus Plugin ID 99325
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.
SolutionUpdate the affected packages.
