Package: libutempter0
Version: 1.1.5-2
Severity: normal
Hello,
The wrapper utempter is not world readable:
> % ls -al /usr/lib/utempter/utempter
> -rwx--s--x. 1 root utmp 4940 2009-08-29 13:03 /usr/lib/utempter/utempter
According to Debian policy, executables should be world-readable[1]:
> Setuid and setgid executables should be mode 4755 or 2755 respectively,
> and owned by the appropriate user or group. They should not be made
> unreadable (modes like 4711 or 2711 or even 4111); doing so achieves
> no extra security, because anyone can find the binary in the freely
> available Debian package; it is merely inconvenient.
In my case, I wanted to run debsums (as non root), but it failed with:
> debsums: can't open libutempter0 file /usr/lib/utempter/utempter
> (Permission denied)
