The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - tcpdump: multiple overflow issues in protocol decoding (CVE-2017-5486)

  - Integer underflow in the olsr_print function in tcpdump 3.9.6 through 4.6.2, when in verbose mode, allows     remote attackers to cause a denial of service (crash) via a crafted length value in an OLSR frame.
    (CVE-2014-8767)

  - Multiple Integer underflows in the geonet_print function in tcpdump 4.5.0 through 4.6.2, when in verbose     mode, allow remote attackers to cause a denial of service (segmentation fault and crash) via a crafted     length value in a Geonet frame. (CVE-2014-8768)
