What's the upstream bug reference? I'm adding a reference to the upstream bug. This is going to affect REHL5 also, but I won't file a bug for that until after the embargo (too many embargoed bugs cause trouble) Please add me (david) to the upstream bug and/or post the patch here. Then I can get packages built. Thanks. OK, You're added to the upstream bug. Upstream patch is for D-Bus 0.61 - RHEL-4 ships 0.22. Let me ask upstream. Lifting embargo. This will be fixed in RHSA-2006:0757 An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2007-0008.html |
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.)
