Ubuntu 16.04 LTS / 18.04 LTS : Ghostscript vulnerabilities (USN-4686-1)

high Nessus Plugin ID 144787

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4686-1 advisory.

 It was discovered that Ghostscript incorrectly handled certain image files. If a user or automated system were tricked into processing a specially crafted file, a remote attacker could use this issue to cause Ghostscript to crash, resulting in a denial of service, or possibly execute arbitrary code.

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

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

Solution

Update the affected packages.
