Test ID:1.3.6.1.4.1.25623.1.0.146587
Category:Denial of Service
Title:ISC BIND DoS Vulnerability (CVE-2017-3137) - Linux
Summary:ISC BIND is prone to a denial of service (DoS) vulnerability.
Description:Summary:
ISC BIND is prone to a denial of service (DoS) vulnerability.

Vulnerability Insight:
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.

Vulnerability Impact:
A server which is performing recursion can be forced to exit with
an assertion failure if it can be caused to receive a response containing CNAME or DNAME resource
records with certain ordering. An attacker can cause a denial of service by exploiting this
condition. Recursive resolvers are at highest risk, but authoritative servers are theoretically
vulnerable if they perform recursion.

Affected Software/OS:
BIND 9.9.9-P6, 9.9.10b1 through 9.9.10rc1, 9.10.4-P6, 9.10.5b1
through 9.10.5rc1, 9.11.0-P3, 9.11.1b1 through 9.11.1rc1 and 9.9.9-S8.

Solution:
Update to version 9.9.9-P8, 9.9.10rc3, 9.10.4-P8, 9.10.5rc3,
9.11.0-P5, 9.11.1rc3, 9.9.9-S10 or later.

CVSS Score:
