"The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2858
advisory.

    An issue has been found in libzip, a library for reading, creating, and modifying zip archives. Crafted
    ZIP archives could allow remote attackers to cause denial of service due to memory allocation failure by
    mishandling EOCD records. For Debian 9 stretch, this problem has been fixed in version 1.1.2-1.1+deb9u1.
    We recommend that you upgrade your libzip packages. For the detailed security status of libzip please
    refer to its security tracker page at: https://security-tracker.debian.org/tracker/libzip Further
    information about Debian LTS security advisories, how to apply these updates to your system and frequently
    asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
