Note that there are TWO places in kdelibs which are affected and have been fixed, one in KSSL and one in kio_http.
I need to check the kdelibs3 code to see whether it is affected too. I suspect it probably is.
I can tell from a first cursory look that kdelibs3 appears to be vulnerable to both the kdelibs issues too. Affected files:
(Qt 3's QLabel also defaults to AutoText mode.)
In both cases, the code is different from the kdelibs 4 code and the patches will have to be ported/rewritten.

This is my proposed patch for the KSSL part of the issue.
I have NOT done ANY testing on this so far. And I'm not sure whether we even CAN test this properly in Fedora. There isn't all that much left using kdelibs3 in Fedora. Testing this on RHEL 5's Konqueror is probably more useful.

And this is my backport of the kio_http fix from kdelibs 4.
Here too, testing is needed.
Qt 3 has no Qt::escape function, so, even though we are linking in all of qt-mt, we still need a custom htmlEscape function. (In kdelibs 4, it's needed because Qt::escape is in QtGui.)
i have reviewed the kevin's patches. both look fine. I will test it today or tomorrow. Kevin, thanks for the backported patches!

CVE-2011-3365 kdelibs: input validation
there're some syntax errors in kevin's patch, i fixed it so that it's compiled fine now. The security patches fixed also the issues.
Thanks for fixing my errors (I forgot the d-pointers, that's what happens when I'm too busy to test that the stuff actually compiles… but I got quite close ;-) ).
