It was discovered that process_crash() in data/apport in Canonical's Apport crash reporting tool may create crash files with incorrect group ownership, possibly exposing crash information beyond expected or intended groups.•CVE-2025-5467
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 `_check_global_pid_and_forward`, which detects if the crashing process resided in a container, was being called before `consistency_checks`, 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. `consistency_checks` is now being called before `_check_global_pid_and_forward`. Additionally, given that the PID-reuse race condition cannot be reliably detected from userspace alone, crashes are only forwarded to containers if the kernel provided a pidfd, or if the crashing process was unprivileged (i.e., if dump mode == 1).•CVE-2025-5054
gdbus setgid privilege escalation•CVE-2020-11936
Apport can be tricked into connecting to arbitrary sockets as the root user•CVE-2022-1242
There is a race condition in the 'replaced executable' detection that, with the correct local configuration, allow an attacker to execute arbitrary code as root.•CVE-2021-3899
