Public bug reported: Please sync bubblewrap 0.4.1-1 (main) from Debian unstable (main)
The sync includes the security fix, which is already included in 0.4.0-1ubuntu4, and other minor fixes. https://github.com/containers/bubblewrap/releases/tag/v0.4.1 - Always clear the capability bounding set (cosmetic issue) - Make the tests work with libcap >= 2.29 - Properly report child exit status in some cases Alexander Larsson (9): Ensure we're always clearing the cap bounding set Don't rely on geteuid() to know when to switch back from setuid root Don't support --userns2 in setuid mode drop_privs: More explicit argument name Christian Kastner (1): tests: Update output patterns for libcap >= 2.29 Jean-Baptiste BESNARD (1): retcode: fix return code with syncfd and no event_fd TomSweeneyRedHat (1): Add Code of Conduct Explanation of the Ubuntu delta and why it can be dropped: * SECURITY UPDATE: privilege escalation when used in setuid mode - debian/patches/CVE-2020-5291.patch: don't rely on geteuid() to know when to switch back from setuid root in bubblewrap.c. - CVE-2020-5291 * d/p/update-output-patterns-libcap-2.29.patch: cherry-pick fix proposed fix to capability drop-related tests, which broke with newer libcap2. * No-change rebuild with fixed binutils on arm64. * Make autopkgtests cross-test-friendly. All changes are now in Debian. Changelog entries since current focal version 0.4.0-1ubuntu4: bubblewrap (0.4.1-1) unstable; urgency=high * New upstream release - Fixes a root privilege escalation vulnerability introduced in 0.4.0, in cases where the kernel allows creation of user namespaces by unprivileged users and bwrap is (unnecessarily) setuid root. Debian systems are vulnerable if /proc/sys/kernel/unprivileged_userns_clone (default 0) has been changed to 1, or if using an upstream kernel instead of a Debian kernel. Ubuntu systems are not normally vulnerable, because bwrap is not normally setuid there. (GHSA-j2qp-rvxj-43vj, CVE ID pending) - Fixes test failure with libcap >= 2.29 (Closes: #951577) * Update various URLs from https://github.com/projectatomic/bubblewrap to https://github.com/containers/bubblewrap * Set upstream metadata fields: Repository. * Remove obsolete field Name from debian/upstream/metadata (already present in machine-readable debian/copyright). * Standards-Version: 4.5.0 (no changes required) * d/tests/control: Qualify CLI tools with :native.
