Package : flatpak
CVE ID : CVE-2021-43860 CVE-2022-21682
Several vulnerabilities were discovered in Flatpak, an application
deployment framework for desktop apps.
CVE-2021-43860
Ryan Gonzalez discovered that Flatpak didn't properly validate
that the permissions displayed to the user for an app at install
time match the actual permissions granted to the app at
runtime. Malicious apps could therefore grant themselves
permissions without the consent of the user.
CVE-2022-21682
Flatpak didn't always prevent a malicious flatpak-builder user
from writing to the local filesystem.
For the stable distribution (bullseye), these problems have been fixed
in version 1.10.7-0+deb11u1.
Please note that flatpak-builder also needed an update for
compatibility, and is now at version 1.0.12-1+deb11u1 in bullseye.
We recommend that you upgrade your flatpak and flatpak-builder
packages.
