Language:

Synopsis

The remote Fedora host is missing a security update.

Description

- 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).

- Supports the check-ID None and fixes 'Checksum None is invalid' [issue #27](https://github.com/ulikunitz/xz/issues/27).

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 golang-github-ulikunitz-xz package.
