Fedora 29 : flatpak (2018-2f9521c82e)

high Nessus Plugin ID 120327

Synopsis

The remote Fedora host is missing a security update.

Description

flatpak 1.0.6 release.

This release fixes an issue that lets system-wide installed applications create setuid root files inside their app dir (somewhere in /var/lib/flatpak/app). Setuid support is disabled inside flatpaks, so such files are only a risk if the user runs them manually outside flatpak.

Installing a flatpak system-wide is needs root access, so this isn't a privilege elevation for non-root users, and allowing root to install setuid files is something all traditional packaging systems allow.
However flatpak tries to be better than that, in order to make it easier to trust third-party repositories.

Changes in this version :

 - The permissions of the files created by the apply_extra script is canonicalized and the script itself is run without any capabilities.

 - Better matching of existing remotes when the local and remote configuration differs wrt collection ids.

 - New flatpakrepo DeployCollectionID replaces CollectionID, doing the same thing. It is recommended to use this instead because older versions of flatpak has bugs in the support of collection ids, and this key will only be respected in versions where it works.

 - The X11 socket is now mounted read-only.

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 flatpak package.
