CVE-2014-5284

Estado: ModificadaAlta (7.2)—

host-deny.sh in OSSEC before 2.8.1 writes to temporary files with predictable filenames without verifying ownership, which allows local users to modify access restrictions in hosts.deny and gain root privileges by creating the temporary files before automatic IP blocking is performed.
