Comment 1 Christian Faulhammer (RETIRED) gentoo-dev 2009-02-13 10:35:19 UTC
Ebuild in the tree, arches please mark net-misc/tor-2.0.33 stable.  Jesse, thanks for your notice...please open a new bug if you find a new issue. draft for the GLSA is now obsolete, as this bug should be handled there, too.  And by the way, bugs should be filed with a full package atom cat-egory/package to make search easier. :)
Comment 2 Christian Faulhammer (RETIRED) gentoo-dev 2009-02-13 10:35:44 UTC
Of course I mean

Comment 6 Robert Buchholz (RETIRED) gentoo-dev 2009-02-13 17:06:28 UTC
This only looks like Denial of Service issues, so rating B3. Can someone help me understand what the "Bugfix on" etc. parts mean? Is that the version the bug was introduced?
Comment 7 Markus Meier gentoo-dev 2009-02-15 11:05:04 UTC
amd64/x86 stable, all arches done.

 all vulnerable versions removed, please proceed for GLSA voting.
Comment 9 Raphael Marichez (Falco) (RETIRED) gentoo-dev 2009-02-22 00:00:50 UTC
i would vote "no" because these bugs can not be easily triggered, they are close to "client-side DoS, triggered by a malicious server or relay", which does not deserve a GLSA as for me.
Comment 10 Robert Buchholz (RETIRED) gentoo-dev 2009-02-25 16:59:19 UTC
It's easy to combine with existing GLSA draft and the exit node issue is a daemon crash. Furthermore, note that inserting malicious nodes into the network is easer than in server-client models.
Comment 11 Stefan Behte (RETIRED) gentoo-dev Security 2009-02-26 22:25:28 UTC
It's very easy to set up a server!
Voting YES, too.
Comment 12 Raphael Marichez (Falco) (RETIRED) gentoo-dev 2009-03-01 14:00:42 UTC
ok (yes-glsa)

 Robert, do you want me to rework my GLSA draft or will you add these new vulnerabilites?
Comment 14 Robert Buchholz (RETIRED) gentoo-dev 2009-03-07 00:20:05 UTC
We'll edit this in GLSAmaker, but you sure can sign up for an account :-)
