Package : libxfont
Version : 1:2.0.1-3+deb9u2
CVE ID : CVE-2017-16611

n issue has been found in libxfont, an X11 font rasterisation library.
By creating symlinks, a local attacker can open (but not read) local files
as user root. This might create unwanted actions with special files like
/dev/watchdog.

1:2.0.1-3+deb9u2.

We recommend that you upgrade your libxfont packages.
