Red Hat Security Advisory - tmpwatch as shipped in Red Hat Linux 6.1, 6.2, and 7.0 uses fork() to recursively process subdirectories, enabling a local user to perform a denial of service attack. Tmpwatch from Red Hat Linux 6.2 and 7.0 also contains an option to allow it to use the fuser command to check for open files before removal. It executed fuser in an insecure fashion, allowing a local root exploit.
