"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2016-129:01 advisory.

    PostgreSQL is an advanced Object-Relational database management system
    (DBMS) that supports almost all SQL constructs (including
    transactions, subselects and user-defined types and functions). The
    postgresql package includes the client programs and libraries that
    you'll need to access a PostgreSQL DBMS server.  These PostgreSQL
    client programs are programs that directly manipulate the internal
    structure of PostgreSQL databases on a PostgreSQL server. These client
    programs can be located on the same machine with the PostgreSQL
    server, or may be on a remote machine which accesses a PostgreSQL
    server over a network connection. This package contains the docs
    in HTML for the whole package, as well as command-line utilities for
    managing PostgreSQL databases on a PostgreSQL server.
    If you want to manipulate a PostgreSQL database on a local or remote PostgreSQL
    server, you need this package. You also need to install this package
    if you're installing the postgresql-server package.
    Security issues fixed with this release:
    CVE-2016-0773
    PostgreSQL before 9.1.20, 9.2.x before 9.2.15, 9.3.x before 9.3.11,
    9.4.x before 9.4.6, and 9.5.x before 9.5.1 allows remote attackers to
    cause a denial of service (infinite loop or buffer overflow and crash)
    via a large Unicode character range in a regular expression.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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