Description Murray McAllister 2014-03-17 06:17:37 UTC
Adrian Panasiuk discovered that the KDirStat (KDE Directory Statistics) tool did not correctly escape quotes when deleting a directory permanently. Attempting to use KDirStat to permanently delete a directory that has a malicious name could result in arbitrary command execution. The original report is regarding single quotes. Testing with the Fedora revealed the issue there was with double quotes. Original report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741659

(In reply to Dmitrij S. Kryzhevich from comment #7) > I did lost "CVE-2014-2527 CVE-2014-2528" from "Summary" but can't found how > to resturn this change. Hello, Thanks for looking at this. I have put it back in the summary (there is an "edit" button near the title of the page). For bugs like this one (filed against the Security Response Product), we leave them in the "NEW" state until everywhere is fixed, and don't assign them to people. For the trackers/product specific bugs, such as bug 1077061 and bug 1077060, you can change their state and assign those to yourself. http://seclists.org/oss-sec/2014/q1/590 has some discussion about the issue. I am unsure if there is a patch yet for the use of " characters :(
Comment 9 Dmitrij S. Kryzhevich 2014-03-19 09:55:14 UTC
Thanks. I think we could use upstream patch as is ( http://paste.fedoraproject.org/86626/52224521/ ) Gained var "QString expanded" just go to shell in the way it is formatted so there no need to make difference between ' and " in this part of code. Substitution for file/directory name go to the following sting: rm -rf %p There are no any spectial signs here. But still I will run few tests. And one more. It was a suprise for me that there is a new upstream here ( bitbucket.org/jeromerobert/k4dirstat ).

Too many mistypes. My bad.
Comment 11 Dmitrij S. Kryzhevich 2014-03-20 03:20:08 UTC
Looks like this patch fix all ' and " issues. Will submit as update.
