The remote host is affected by the vulnerability described in GLSA-201706-15 (WebKitGTK+: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in WebKitGTK+. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attack can use multiple vectors to execute arbitrary code or       cause a denial of service condition.
  Workaround :

    There is no known workaround at this time.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The regex code in Webkit 2.4.11 allows remote attackers to cause a denial of service (memory consumption)     as demonstrated in a large number of ($ (open parenthesis and dollar) followed by {-2,16} and a large     number of +) (plus close parenthesis). (CVE-2016-9643)

Note that Nessus relies on the presence of the package as reported by the vendor.
