Package : tenshi
Version : 0.13-2+deb7u1
CVE ID : CVE-2017-11746
Debian Bug : 871321

Tenshi creates a tenshi.pid file after dropping privileges to a non-root
account, which might allow local users to kill arbitrary processes by
leveraging access to this non-root account for tenshi.pid modification before a
root script executes a "kill cat /pathname/tenshi.pid" command.

For Debian 7 "Wheezy", these problems have been fixed in version
0.13-2+deb7u1.

We recommend that you upgrade your tenshi packages.
