The seunshare_mount function in sandbox/seunshare.c in seunshare in certain Red Hat packages of policycoreutils 2.0.83 and earlier in Red Hat Enterprise Linux (RHEL) 6 and earlier, and Fedora 14 and earlier, mounts a new directory on top of /tmp without assigning root ownership and the sticky bit to this new directory, which allows local users to replace or delete arbitrary /tmp files, and consequently cause a denial of service or possibly gain privileges, by running a setuid application that relies on /tmp, as demonstrated by the ksu application.

Security readout for executives and security teams

This is an old local Linux flaw in Red Hat policycoreutils seunshare. On affected RHEL and Fedora systems, seunshare could make /tmp behave unsafely, letting a local user delete or replace files there. Business impact is mainly service disruption, with possible privilege gain when vulnerable setuid programs rely on /tmp. Exposure is most likely on legacy RHEL 6-or-earlier and Fedora 14-or-earlier systems with affected Red Hat policycoreutils packages installed. Modern maintained hosts are less likely exposed if vendor updates were applied. Prioritize remediation for any still-running legacy Red Hat or Fedora systems with multiple local users. This is not a modern internet-facing emergency based on the supplied evidence, but unpatched legacy shared hosts deserve prompt cleanup. Mitigation focus: Apply the Red Hat or Fedora policycoreutils updates referenced by vendor advisories.; Inventory legacy RHEL and Fedora hosts for affected policycoreutils versions.; Limit local shell access on systems that cannot be immediately updated..
