Fedora Security Alert for nbdkit v1.24.6 mitigates severe injection vulnerability CVE-2021-3716 safeguarding system stability.
New upstream stable version 1.24.6; fixes CVE-2021-3716.

Summary

NBD is a protocol for accessing block devices (hard disks and

disk-like things) over the network.

nbdkit is a toolkit for creating NBD servers.

The key features are:

* Multithreaded NBD server written in C with good performance.

* Minimal dependencies for the basic server.

* Liberal license (BSD) allows nbdkit to be linked to proprietary

libraries or included in proprietary code.

* Well-documented, simple plugin API with a stable ABI guarantee.

Lets you to export "unconventional" block devices easily.

* You can write plugins in C or many other languages.

* Filters can be stacked in front of plugins to transform the output.

'nbdkit' is a meta-package which pulls in the core server and a

useful subset of plugins and filters with minimal dependencies.

If you want just the server, install 'nbdkit-server'.

To develop plugins, install the 'nbdkit-devel' package and start by

reading the nbdkit(1) and nbdkit-plugin(3) manual pages.

New upstream stable version 1.24.6; fixes CVE-2021-3716.
