Adding new fonts for all users

To install fonts for all users

for example the boring company font:

one need to login as root and create a directory under

# tested on
Static hostname: centos.localdomain
Chassis: laptop
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 4.15.9
Architecture: x86-64

# in combination with:

su - root; # become root
# change into dir
cd /usr/share/fonts/;
# download font
# unpack
# seems spaces in filename is no good
mv "futura bold" "futura-bold";
# so one got now this new dir:
ll /usr/share/fonts/futura-bold
total 248K
drwxr-xr-x. 2 root root 179 Dec 15 14:49 .
drwxr-xr-x. 45 root root 4.0K Dec 15 14:49 ..
-rwxr-xr-x. 1 root root 38K Aug 9 2015 Futura Bold.ttf
-rwxr-xr-x. 1 root root 41K Aug 5 2015 Futura Extra Bold.ttf
-rwxr-xr-x. 1 root root 49K Aug 5 2015 Futura Round Bold.ttf
-rwxr-xr-x. 1 root root 28K Aug 5 2015 FuturaStd Bold.ttf
-rwxr-xr-x. 1 root root 28K Aug 5 2015 Futura Std Extra Bold.ttf
-rwxr-xr-x. 1 root root 49K Aug 5 2015 Futura URW Extra Bold.ttf

# change permission rights
# VERY IMPORTANT OR LibreOffice will not be able to access the font
chmod -R ugo+rx futura-bold
# or on the whole directory
chmod -R ugo+rx /usr/share/fonts/
# now run this: # build font information cache files
fc-cache -f /usr/share/fonts/

result should look like this:

can ttf font files contain malicious code?

for Windows: yes?

for Appe Mac OSX: yes?

CVE-2016-1797 : “Apple Type Services (ATS) in Apple OS X before 10.11.5 allows attackers to bypass intended FontValidator sandbox-policy restrictions and execute arbitrary code in a privileged context via a crafted app.”

for linux? have no idea


while for Ubuntu / Debian a program exists called “font-manager”, no such thing seems to exist: yum search font-manager (nothing found)
