Fedora 31 : bubblewrap (2020-a4206f14f1)

high Nessus Plugin ID 135600

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

Update to 0.4.1

This release fixes a privilege escalation bug pointed out by Stephen Röttger, where in some setups bubblewrap can be used to gain root permissions. Only version 0.4.0 is vulnerable, and only if installed setuid while at the same time the kernel supports unprivileged user namespaces. More details in the advisory here :

[GHSA-j2qp-rvxj-43vj](https://github.com/containers/bubblewrap/securit y/advisories/GHSA-j2qp-rvxj-43vj)

Additionally there are some minor changes :

 - Always clear the capability bounding set (cosmetic issue)

 - Make the tests work with libcap >= 2.29

 - Properly report child exit status in some cases

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 bubblewrap package.
