There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - An information leak vulnerability was found in Undertow. If all headers are not written out in the first
    write() call then the code that handles flushing the buffer will always write out the full contents of the
    writevBuffer buffer, which may contain data from previous requests. (CVE-2018-14642)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0364 advisory.
