Synopsis

The remote Fedora host is missing a security update.

Description

This update of `expat` fixes the following security issue :

 - **CVE-2019-15903** -- Fix heap overflow triggered by `XML_GetCurrentLineNumber` (or `XML_GetCurrentColumnNumber`), and deny internal entities closing the doctype

The following bug fixes are also included :

 - Fix cases where `XML_StopParser` did not have any effect when called from inside of an end element handler

 - xmlwf: Fix exit code for operation without '`-d DIRECTORY`' previously, only '`-d DIRECTORY`' would give you a proper exit code

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

Solution

Update the affected expat package.
