The mxml_write_node function in mxml-file.c in mxml 2.9, 2.7, and possibly earlier allows remote attackers to cause a denial of service (stack consumption) via crafted xml file.

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

  - The mxml_write_node function in mxml-file.c in mxml 2.9, 2.7, and possibly earlier allows remote attackers     to cause a denial of service (stack consumption) via crafted xml file. (CVE-2016-4571)

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

Several stack exhaustion conditions were found in mxml that can easily crash when parsing xml files.
