Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-6354-1 advisory.

 It was discovered that Python did not properly handle XML entity declarations in plist files. An attacker could possibly use this vulnerability to perform an XML External Entity (XXE) injection, resulting in a denial of service or information disclosure.

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