Problem description

mm/libmm is a shared library that provides an easy API for shared memory operations and inter process communication (SYSV-IPC). The file under /tmp that libmm uses to communicate over is being created insecurely, leading the process using libmm to a security problem with overwriting files owned by the user running the the process. In particular, this weakness enables an attacker who has already obtained the userID wwwrun (the user that the apache webserver runs as) to gain local root privileges.
