-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Format: 1.8 Date: Wed, 26 Aug 2026 12:04:21 +0100 Source: bubblewrap Architecture: source Version: 0.12.0-1~deb13u1 Distribution: trixie-security Urgency: high Maintainer: Utopia Maintenance Team Changed-By: Simon McVittie Closes: 1145655 Changes: bubblewrap (0.12.0-1~deb13u1) trixie-security; urgency=high . * Merge new upstream release from unstable - Prevent sandbox escape via symlink traversal. If an app framework such as Flatpak mounts subdirectories into a directory controlled by the sandboxed app, a malicious or compromised sandboxed app could create symlinks in that directory to arrange for files/directories to be created on the host system. (GHSA-pxhw-h44j-8pfx, no known CVE ID; Closes: #1145655) - bubblewrap no longer supports running when setuid, matching the upstream default. This ensures that vulnerabilities similar to CVE-2026-41163 can't happen in future. * Debian 13 backport changes: - d/control, d/gbp.conf: Branch for Debian 13 stable updates - Revert packaging changes that are not appropriate for a stable release * Packaging changes since 0.11.0-2+deb13u1: - d/rules: Stop passing -Dsupport_setuid=false. The option no longer exists, and the new version of bubblewrap always behaves as though its value was false. - d/rules: Don't compile fallback code paths for kernel older than 5.10. This ensures that we're using the safest available mechanisms, using the openat2() syscall rather than emulating it in user-space. As a result, this version will not work on kernels older than the one found in Debian 11. - d/rules: Install NEWS.md as the upstream changelog - d/p/CVE-2026-41163/: Drop patches, no longer needed/applicable with the new upstream release - d/p/debian/Change-EPERM-error-message-to-show-Debian-specific-inform.patch: Adjust patch to apply to the new upstream release - d/README.Debian: Rewrite to reflect that setuid is no longer supported - d/copyright: Update license from LGPL-2+ to LGPL-2.1+, matching upstream . bubblewrap (0.12.0-1) unstable; urgency=high . * New upstream release - Prevent sandbox escape via symlink traversal.
