 Package : flatpak CVE ID : CVE-2024-42472

 Chris Williams discovered a flaw in the handling of mounts for persistent directories in Flatpak, an application deployment framework for desktop apps. A malicious or compromised Flatpak app using persistent directories could take advantage of this flaw to access files outside of the sandbox.

 Details can be found in the upstream advisory at https://github.com/flatpak/flatpak/security/advisories/GHSA-7hgv-f2j8-xw87

 For the stable distribution (bookworm), this problem has been fixed in version 1.14.10-1~deb12u1. To address the vulnerability, flatpak uses a new feature provided in bubblewrap and provided in version 0.8.0-2+deb12u1 along with this update.

 We recommend that you upgrade your flatpak packages.

 For the detailed security status of flatpak please refer to its security tracker page at:
