"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2015-557:03 advisory.

    Provides a set of daemons to manage access to remote directories and
    authentication mechanisms. It provides an NSS and PAM interface toward
    the system and a pluggable backend system to connect to multiple different
    account sources. It is also the basis to provide client auditing and policy
    services for projects like FreeIPA.
    Security issues fixed with this release:
    CVE-2015-5292
    Memory leak in the Privilege Attribute Certificate (PAC) responder
    plugin (sssd_pac_plugin.so) in System Security Services Daemon (SSSD)
    1.10 before 1.13.1 allows remote authenticated users to cause a denial
    of service (memory consumption) via a large number of logins that
    trigger parsing of PAC blobs during Kerberos authentication.
    Fixed bugs:
    * Previously, SSSD did not correctly handle sudo rules that applied to groups with names containing
    special characters, such as the ( opening parenthesis sign. Consequently, SSSD skipped such sudo rules.
    The internal sysdb search has been modified to escape special characters when searching for objects to
    which sudo rules apply. As a result, SSSD applies the described sudo rules as expected.
    * Prior to this update, SSSD did not correctly handle group names containing special Lightweight Directory
    Access Protocol (LDAP) characters, such as the ( or ) parenthesis signs. When a group name contained
    one or more such characters, the internal cache cleanup operation failed with an I/O error. With this
    update, LDAP special characters in the Distinguished Name (DN) of a cache entry are escaped before the
    cleanup operation starts. As a result, the cleanup operation completes successfully in the described
    situation.
    * Applications performing Kerberos authentication previously increased the memory footprint of the
    Kerberos plug-in that parses the Privilege Attribute Certificate (PAC) information. The plug-in has been
    updated to free the memory it allocates, thus fixing this bug.
    * Previously, when malformed POSIX attributes were defined in an Active Directory (AD) LDAP server, SSSD
    unexpectedly switched to offline mode. This update relaxes certain checks for AD POSIX attribute validity.
    As a result, SSSD now works as expected even when malformed POSIX attributes are present in AD and no
    longer enters offline mode in the described situation.

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.");
