"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2016-091:01 advisory.

    The glibc package contains standard libraries which are used by
    multiple programs on the system. In order to save disk space and
    memory, as well as to make upgrading easier, common system code is
    kept in one place and shared between programs. This particular package
    contains the most important sets of shared libraries: the standard C
    library and the standard math library. Without these two libraries, a
    Linux system will not function.
    Security issues fixed with this release:
    CVE-2015-7547
    ** 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.
    Fixed bugs:
    * The dynamic loader has been enhanced to allow the loading of more shared libraries that make use of
    static thread local storage. While static thread local storage is the fastest access mechanism it may also
    prevent the shared library from being loaded at all since the static storage space is a limited and shared
    process-global resource. Applications which would previously fail with dlopen: cannot load any more
    object with static TLS should now start up correctly.
    * A bug in the POSIX realtime support would cause asynchronous I/O or certain timer API calls to fail and
    return errors in the presence of large thread-local storage data that exceeded PTHREAD_STACK_MIN in size
    (generally 16 KiB). The bug in librt has been corrected and the impacted APIs no longer return errors when
    large thread-local storage data is present in the application.

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.");
