Description Jan Lieskovsky 2009-06-17 12:22:31 UTC
An integer overflow, leading to heap-based buffer overflow was found
in the KDE implementation of garbage collector for the JavaScript 
language (KJS). An remote attacker could use this flaw to cause a denial
of service (konqueror crash), or potentially, execute arbitrary code with
the privileges of the user running "konqueror" web browser, if the
victim visited a specially-crafted HTML page.

Comment 8 Kevin Kofler 2009-07-25 22:47:37 UTC
This also affects kdelibs3 3.5.10 and appears to affect kdelibs 4.2.4 in Fedora.

Comment 9 Kevin Kofler 2009-07-25 23:11:31 UTC
(Note that this is NOT fixed in KDE trunk.)

Comment 10 Kevin Kofler 2009-07-26 00:07:32 UTC
For QtWebKit, this is fixed in Qt 4.5.2 which got pushed to Fedora updates recently. I didn't check earlier versions.

Comment 11 Kevin Kofler 2009-07-26 02:01:25 UTC
Unfortunately, the WebKit patch, while fixing the integer overflow, still allows DoSing the browser, it just aborts if it would overflow. :-(

Untested patch against kdelibs 4.2.98

Here's an untested patch against kdelibs 4.2.98. Like the WebKit patch, this just crashes if we would overflow. IMHO, doing things right would mean throwing an error somehow, but I don't understand the code well enough to do that.
