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

  - perl-XML-Twig: The option to `expand_external_ents`, documented as controlling external entity expansion     in XML::Twig does not work. External entities are always expanded, regardless of the option's setting.
    (CVE-2016-9180)

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

According to the version of the perl-XML-Twig package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - perl-XML-Twig: The option to `expand_external_ents`,     documented as controlling external entity expansion in     XML::Twig does not work. External entities are always     expanded, regardless of the option's     setting.(CVE-2016-9180)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update for perl-XML-Twig fixes the following issues :

  - Security fix [bsc#1008644, CVE-2016-9180]

  - Setting expand_external_ents to 0 or -1 currently     doesn't work as expected; To completely turn off     expanding external entities use no_xxe.

  - Update documentation for XML::Twig to mention problems     with expand_external_ents and add information about new     no_xxe argument

This update was imported from the SUSE:SLE-15:Update update project.
