## Description

Race condition in Canonical apport up to and including 2.32.0 allows alocal attacker to leak sensitive information via PID-reuse by leveragingnamespaces.When handling a crash, the function `_check_global_pid_and_forward`, whichdetects if the crashing process resided in a container, was being calledbefore `consistency_checks`, which attempts to detect if the crashingprocess had been replaced. Because of this, if a process crashed and wasquickly replaced with a containerized one, apport could be made to forwardthe core dump to the container, potentially leaking sensitive information.`consistency_checks` is now being called before`_check_global_pid_and_forward`. Additionally, given that the PID-reuserace condition cannot be reliably detected from userspace alone, crashesare only forwarded to containers if the kernel provided a pidfd, or if thecrashing process was unprivileged (i.e., if dump mode == 1).
