Package: ca-certificates
Version: 20180409
Severity: normal
Dear Maintainer,
* What led up to the situation?
my /usr/local dir is a symlink to /srv/local
* What exactly did you do (or not do) that was effective (or ineffective)?
after a
dpkg-reconfigure ca-certificates
the directory /srv/local/share/ca-certificates becames world writable!
Here is an example session
# ls -flad / /usr /usr/local /srv/local /srv/local/share
/srv/local/share/ca-certificates
drwxr-xr-x 24 root root 4096 Dec 6 17:19 /
drwxr-xr-x 9 root root 4096 Dec 2 16:54 /usr
lrwxrwxrwx 1 root root 10 Dec 2 16:54 /usr/local -> /srv/local
drwxr-xr-x 16 root root 4096 Dec 2 16:50 /srv/local
drwxrwsr-x 8 root staff 4096 Dec 19 10:01 /srv/local/share
drwxr-sr-x 2 root root 4096 Dec 19 09:26
/srv/local/share/ca-certificates

# ls -flad / /usr /usr/local /srv/local /srv/local/share
/srv/local/share/ca-certificates
drwxr-xr-x 24 root root 4096 Dec 6 17:19 /
drwxr-xr-x 9 root root 4096 Dec 2 16:54 /usr
lrwxrwxrwx 1 root root 10 Dec 2 16:54 /usr/local -> /srv/local
drwxr-xr-x 16 root root 4096 Dec 2 16:50 /srv/local
drwxrwsr-x 8 root staff 4096 Dec 19 10:01 /srv/local/share
drwxrwsrwx 2 root root 4096 Dec 19 09:26
/srv/local/share/ca-certificates
Note the changed permission of /srv/local/share/ca-certificates
drwxr-sr-x -> drwxrwsrwx
* What outcome did you expect instead?
keep a safe permission
* Possible correction
The problem seems to be in
/var/lib/dpkg/info/ca-certificates.postinst
the stat command should have the '-L' switch
So for example:
chmod $(stat -c %a /usr/local) /usr/local/share/ca-certificates
chown $(stat -c %u /usr/local):$(stat -c %g /usr/local)
/usr/local/share/ca-certificates
should became
chmod $(stat -c %a -L /usr/local) /usr/local/share/ca-certificates
chown $(stat -c %u -L /usr/local):$(stat -c %g -L /usr/local)
/usr/local/share/ca-certificates
