Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-3404-2 advisory.

- The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel through 4.11.1 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface. (CVE-2017-7487)

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