Enhancements:
-
The flag --not-a-security-boundary was added. If this is enabled
then failure of some sandbox setup steps (like remounting a
submount) are not fatal. -
The license has been updated from LGPL 2.0 (or later) to LGPL 2.1
(or later). -
This version removes the support for building a setuid
bubblewrap. Changes in this version made it difficult to support
and basically all modern linux distributions now support
unprivileged user namespaces to some extent. -
The assume_kernel build option was added, if specified no backwards
compatiblity for kernels older than this is built in (and will result
in hard failures at runtime). Currently specifying 5.6.0 or
later will disable the fallback implementation of
openat2(RESOLVE_IN_ROOT).
Bug fixes:
- Bubblewrap now correctly resolves absolute symlinks during the
sandbox setup by using openat2 with RESOLVE_IN_ROOT (or a fallback
implementation). This fixes a security issue (GHSA-pxhw-h44j-8pfx)
where file or directories created during sandbox setup could
follow parent symlinks out of the sandbox.
