"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2014-041:01 advisory.

    OpenLDAP is an open source suite of LDAP (Lightweight Directory Access Protocol) applications and
    development tools. LDAP is a set of protocols for accessing directory services (usually phone book style
    information, but other information is possible) over the Internet, similar to the way DNS (Domain Name
    System) information is propagated over the Internet. The openldap package contains configuration files,
    libraries, and documentation for OpenLDAP.
    Security issues fixed with this release:
     CVE-2013-4449
    The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier does not properly count references, which allows
    remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search
    request, which triggers rwm_conn_destroy to free the session context while it is being used by
    rwm_op_search.
    Fixed bugs:
     Previously, sending parallel update requests to the server could trigger a deadlock. This has been fixed
    and OpenLDAP now handles simultaneous updates as expected.

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.");
