Description Josh Bressers 2006-12-14 13:11:33 EST
+++ This bug was initially created as a clone of Bug #218055 +++

Kimmo Hämäläinen reported a DoS flaw in D-Bus to the freedesktop.org
bugzilla.  To quote his bug:

        I found a nasty bug from match_rule_equal() that can cause matches
        to be removed from another connections (thanks goes to other guys
        for finding reproducable use case for the bug).

This flaw can cause a local user to disable the the ability of another
process to receive certain messages.  This flaw does not contain any
potential for arbitrary code execution.  Here is a more details description
from Kimmo:

        We don't have the software public yet, but the use case was the
        following.  There are three processes A, B, and C. All of them add
        the same match (same value). A is started first, then B, and lastly
        C. Now, B and C are closed: if B is closed before C, A's match is
        removed; but if C is closed before B, A's match is not removed (no
        buggy behaviour). (B and C call dbus_bus_remove_match on exit.)

David: Probably the issue is fixed in dbus-1.0.1-12.fc6, right? Is there any
reason for not closing this bug?
