CVE-2013-4288 [HIGH] CVE-2013-4288 polkit: unix-process subject for authorization is racy
CVE-2013-4288 polkit: unix-process subject for authorization is racy
Sebastian Krahmer reported a race condition in the polkit unix-process subject for authorization. It depended on the (PID, startup_time) pair to be passed to pokkit, which then used /proc/PID/status to find the UID the process belongs to. A local attacker could exploit this issue via a polkit enabled application, by starting a suid or pkexec process, changing the eud and/or uid at will. This could result in bypass polkit authorizations or even privilege escalation in some cases.
