Latest Projectatomic Bubblewrap Security Vulnerabilities
Bubblewrap (bwrap) before version 0.4.1
7.8 - High
- March 31, 2020
Bubblewrap (bwrap) before version 0.4.1, if installed in setuid mode and the kernel supports unprivileged user namespaces, then the `bwrap --userns2` option can be used to make the setuid process keep running as root while being traceable. This can in turn be used to gain root permissions. Note that this only affects the combination of bubblewrap in setuid mode (which is typically used when unprivileged user namespaces are not supported) and the support of unprivileged user namespaces. Known to be affected are: * Debian testing/unstable, if unprivileged user namespaces enabled (not default) * Debian buster-backports, if unprivileged user namespaces enabled (not default) * Arch if using `linux-hardened`, if unprivileged user namespaces enabled (not default) * Centos 7 flatpak COPR, if unprivileged user namespaces enabled (not default) This has been fixed in the 0.4.1 release, and all affected users should update.

bubblewrap.c in Bubblewrap before 0.3.3 misuses temporary directories in /tmp as a mount point. In some particular configurations (related to XDG_RUNTIME_DIR), a local attacker may abuse this flaw to prevent other users from executing bubblewrap or potentially execute code.
