Description Colin Walters 2008-09-29 21:02:13 UTC

Upstream bug report:

https://bugs.freedesktop.org/show_bug.cgi?id=17803

It is likely possible to send a message with a malformed signature which would cause the bus (or in general any process using libdbus to receive messages) to abort.

Comment 1 Josh Bressers 2008-09-30 13:48:11 UTC

Do you know what versions of dbus are affected by this?

Comment 2 Colin Walters 2008-10-01 21:02:41 UTC

This code dates at least as far back as:

commit 5e389fdf499c39926c61b47fcafb5e71291ce1a2
Author: John (J5) Palmieri <johnp>
Date:   Wed Jun 15 15:15:32 2005 +0000

Comment 3 Colin Walters 2008-10-01 21:41:40 UTC

According to brew the first build of dbus in RHEL is 2006, so I think this affects both EL4 and EL5.  Does not affect EL3 or earlier as I don't believe DBus is shipped there.

Comment 4 Colin Walters 2008-10-01 21:43:20 UTC

By the way I could use some hand-holding with respect to how this should be handled upstream, things like if/how I allocate a CVE, etc.

Note the bug was filed publicly so we can't embargo or anything like that.

Comment 5 Colin Walters 2008-10-03 21:51:44 UTC

Ping on this - I'd like to do a new upstream release with the fix and could use advice on how to do the announcement and CVE etc.

Comment 6 Josh Bressers 2008-10-04 01:23:48 UTC

Sorry, I let this one slip through the cracks.  We'll deal with it next week.

Comment 7 Josh Bressers 2008-10-06 16:42:48 UTC

I've assigned CVE-2008-3834 to this, and I'm moving this bug to the security-response product.

Comment 16 Tomas Hoger 2008-10-27 13:57:47 UTC

Direct link to upstream patch, as the attachment in comment #10 only contains URL of the upstream commit:
