Fedora 30 : expat (2019-9505c6b555)

high Nessus Plugin ID 129322


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.


The remote Fedora host is missing a security update.


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.


Update the affected expat package.
