Ubuntu 16.04 LTS / 18.04 LTS / 19.04 : Expat vulnerability (USN-4132-1)

high Nessus Plugin ID 128874
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that Expat incorrectly handled certain XML files. An attacker could possibly use this issue to expose sensitive information.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected lib64expat1 and / or libexpat1 packages.
