Fedora 32 : golang-github-ulikunitz-xz (2020-e384830a0d)

high Nessus Plugin ID 140066


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.


- The `readUvarint` function would run infinitely given specific input. The function is now terminating if more than 10 bytes of input have been read. Fixes [issue #35](https://github.com/ulikunitz/xz/issues/35) (CVE-2020-16845).

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 golang-github-ulikunitz-xz package.
