Ubuntu Security Notice USN-7046-1
September 30, 2024

bubblewrap, flatpak vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Flatpak could be made to read and write files in locations it
would not normally have access to.

Software Description:
- bubblewrap: utility for unprivileged chroot and namespace manipulation
- flatpak: Application deployment framework for desktop apps

Details:

It was discovered that Flatpak incorrectly handled certain persisted
directories. An attacker could possibly use this issue to read
and write files in locations it would not normally have access to.
A patch was also needed to Bubblewrap in order to avoid race
conditions caused by this fix.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
bubblewrap 0.9.0-1ubuntu0.1
flatpak 1.14.6-1ubuntu0.1
