Debian Security Advisory

DLA-1069-1 tenshi -- LTS security update

Date Reported:

27 Aug 2017

Affected Packages:

tenshi

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 871321.
In Mitre's CVE dictionary: CVE-2017-11746.

More information:

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.
