            Bug ID: 83591
                CC: lennart at poettering.net
          Assignee: pulseaudio-bugs at lists.freedesktop.org
           Summary: Server crashes if a client tells it to update stream
                    rate when the stream doesn't support that
        QA Contact: pulseaudio-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: tanuk at iki.fi
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: core
           Product: PulseAudio

I haven't tried this in practice, but it seems that the server doesn't check
whether the sink input's or source output's resampler supports rate changes
when a client sends a request to change the stream's rate. When using libpulse,
invalid rate changes are filtered at client side, but a malicious client can
talk to the server without using libpulse.
