While backporting a feature for a newer branch of BIND9, RedHat introduced a path leading to an assertion failure in buffer.c:420. Affects RedHat versions bind-9.9.4-65.el7 -> bind-9.9.4-72.el7. No ISC releases are affected. Other packages from other distributions who made the same error may also be affected.

The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2019-3820:02 advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has bind packages installed that are affected by a vulnerability:

  - ** RESERVED ** This candidate has been reserved by an     organization or individual that will use it when     announcing a new security problem. When the candidate     has been publicized, the details for this candidate will     be provided. (CVE-2018-5742)

Crash from assertion error when debug log level is 10 and log entries meet buffer boundary. This flaw appears to be exploitable only when debug logging is enabled and set to at least a level of 10. As this configuration should be rare in production instances of bind, it is unlikely that most servers will be exploitable. The debug level of the bind server can be checked via the rndc status command, which will return the current trace level as 'debug level'. A value of 10 or above would most likely make this flaw exploitable.(CVE-2018-5742)

An update for bind is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

Security Fix(es) :

* bind: Crash from assertion error when debug log level is 10 and log entries meet buffer boundary (CVE-2018-5742)
