Description Tomas Hoger 2008-04-23 08:01:35 UTC 
Upcoming KDE security advisory:

Systems affected:
	KHTML, as shipped with KDE 4.0 or newer. KDE 3.x is not affected.

Overview:
	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.

Impact:
	A remote site can cause a denial of service and possibly execute
	arbitrary code in the context of the user.

Comment 9 Tomas Hoger 2008-04-28 07:53:47 UTC 
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.
Comment 10 Kevin Kofler 2008-04-28 16:01:08 UTC 
kdelibs-4.0.3-7.fc9 tagged f9-final.
