Exploits Discovered - Published CVE-2017-11746

Title: Tenshi privilege escalation via PID file manipulation

Author: Michael Orlitzky

Fixed in: Commits 46b0148 and d0e7f28; Tenshi 0.16

Tenshi 0.15 and earlier allowed its unprivileged runtime account to control PID information. A later root-run stop operation could therefore be redirected to signal an attacker-selected process.
