Race condition in Canonical apport up to and including 2.32.0 allows a local attacker to leak sensitive information via PID-reuse by leveraging namespaces. When handling a crash, the function , which detects if the crashing process resided in a container, was being called before , which attempts to detect if the crashing process had been replaced. Because of this, if a process crashed and was quickly replaced with a containerized one, apport could be made to forward the core dump to the container, potentially leaking sensitive information. is now being called before .
