Ubuntu 16.04 LTS / 18.04 LTS : Ghostscript vulnerability (USN-4092-1)

high Nessus Plugin ID 127840

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4092-1 advisory.

 Netanel Fisher discovered that the font handler in Ghostscript did not properly restrict privileged calls when '-dSAFER' restrictions were in effect. If a user or automated system were tricked into processing a specially crafted file, a remote attacker could possibly use this issue to access arbitrary files.

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

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

Solution

Update the affected packages.
