Package : bubblewrap CVE ID : not yet available Debian Bug : 1145655

A symlink traversal vulnerability was discovered in bubblewrap, a low-level unprivileged sandboxing tool used by Flatpak and other projects, which could result in sandbox escape by malicious/compromised Flatpak apps.

For the stable distribution (trixie), this problem has been fixed in version 0.12.0-1~deb13u1. This updates bubblewrap to the 0.12 release branch, which no longer supports running bubblewrap as setuid root.
For additional details please refer to the README.Debian.gz file.

We recommend that you upgrade your bubblewrap packages.

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