Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS : pngcheck vulnerabilities (USN-6182-1)

high Nessus Plugin ID 177471

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6182-1 advisory.

 It was discovered that pngcheck incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service.

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 pngcheck package.
