CVE-2008-1670 kdelibs: Buffer overflow in KHTML's image loader
Last modified: 2008-07-25 06:16:15 EDT
Upcoming KDE security advisory:
KHTML, as shipped with KDE 4.0 or newer. KDE 3.x is not affected.
The new progressive PNG Image loader in KHTML of KDE 4.0 and newer
can be tricked into overrunning a heap allocated memory buffer
by loading a specially encoded image.
A remote site can cause a denial of service and possibly execute
arbitrary code in the context of the user.

Upstream bug report: http://bugs.kde.org/show_bug.cgi?id=156623
The fix is present in CVS (both devel and F-9), kdelibs-4.0.3-7
Public now, lifting embargo:
As mentioned in comment #5, this was already fixed in F9 and rawhide. It's
probably worth requesting freeze break for kdelibs-4.0.3-7.fc9.
There are kdelibs4 packages in F7 and F8, that should be affected as well, even
though I'm not sure if there's any application in F7 and F8 that may be using
vulnerable code at the moment.
kdelibs-4.0.3-7.fc9 tagged f9-final.
kdelibs4-4.0.3-7.fc7, qt4-4.3.4-11.fc7, kdebase-runtime-4.0.3-10.fc7.1, kde-filesystem-4-14.fc7, kdebase4-4.0.3-9.fc7, kdepimlibs-4.0.3-3.fc7 has been pushed to the Fedora 7 stable repository. If problems still persist, please make note of it in this bug report.
kde-filesystem-4-14.fc8, kdebase4-4.0.3-9.fc8, kdebase-runtime-4.0.3-10.fc8.1, kdepimlibs-4.0.3-3.fc8, kdelibs4-4.0.3-7.fc8, qt4-4.3.4-11.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report.
