            Bug ID: 102060
           Summary: Security: PulseAudio server weakens the umask
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: daemon
          Assignee: pulseaudio-bugs@lists.freedesktop.org
          Reporter: klaus.kus...@computerix.info

We have a strict umask 077 policy here, i.e. all files created under /home
must have 00 permissions for group and other.

However, in spite of its initial umask being 077, the pulseaudio daemon 
creates files with permissions 644 in $HOME/.config/pulse.

A quick look into the source found a umask(0022); in src/daemon/main.c .

It may create files with more restrictive permissions than the umask says
(e.g. with 644 if the umask is 000), but it must not ignore the initial umask
or set its umask to something weaker than the initial umask,
and it must not create files with less restricive permissions than the umask!
