Re: CVE request for Calligra

Hi Kurt.  

Yes, sorry I didn't report directly to the correct people.  I only knew that the vulnerability existed for sure in the 
Nokia Documents app and also in the version of Koffice I happen to have on my system.  I didn't know what library it 
was in (I'd never even heard of Calligra), if it was already known about upstream, what other software depend on this 
library, etc.  As you're probably aware, it can be a very time consuming process to try to get that stuff sorted out, 
so I just report it to the vendor and let them deal with these issues.  In that spirit, I reported to Nokia early last 
month.  As for your questions, I have not asked for CVE's for any of these vulnerabilities.  Feel free to request them 
yourselves.  I believe the only vulnerability I know enough details about to say is a security issue is the one in the 
document about parsing word documents.  I hope that clears up any questions you might have.  Thanks!

Charlie

Please post the diff between the vulnerable code and the fix so
we are sure that is a security issue.


Hi,

You can read all about the details of the vulnerability in the
Black Hat 2012 presentation by Charlie Miller 
(http://media.blackhat.com/bh-us-12/Briefings/C_Miller/BH_US_12_Miller_NFC_attack_surface_WP.pdf)


- -- details of the Calligra (and KOffice) exploit start at page 39.

Unfortunately, he did not notify us ahead of time of his intent
to disclose, so it's already public.

I suspect he may not have known about it (this is the first time I can
remember hearing of Calligra). Trying to keep track of all possible
project forks is pretty much impossible in the modern Open Source world.

Charlie 1): have you requested CVE #'s for this issue for Koffice?

Charlie 2): it appears there are quite a few other security issues in
the presentation, are they in open source components, if yes can you
please send a CVE request(s) for the issue to oss-security@ so I can
assign CVE's for them? Thanks.

Once Charlie replies (either way) I'll assign CVE's.


Thanks, Jeff
