Description Lubomir Kundrak 2007-09-20 19:42:59 UTC

Description of problem:

Any local user1 can create /tmp/pulse-user2 to effectively prevent user2 from
starting pulseaudio daemon (a local Denial of Service).

Additional info:

/tmp is _not_ the right place for user-specific information that is mean to be
persistent and shared between independent processes. See bug #219281 comment #4
for possible solutions. Apart from those, another solution is using
~/.pulse-hostname. With per-user /tmp which we do not have in supported releases
this problem will disappear.

Ping ping.

Comment 2 Joseph Shraibman 2008-02-15 21:51:25 UTC

This is a problem when my kde session doesn't shut down properly and the old
/tmp/pulse-user directory doesn't get removed.  On my next login my sound isn't
working and I don't know why.

This is a problem for me on Fedora 8.

This bug has been fixed upstream in the "glitch-free" branch will soonishly
become trunk.
