Description Mark J. Cox 2004-02-25 13:35:21 UTC 
Flaws have been found in the cookie path handling between a number of
web browsers and web servers.  The HTTP cookie standard allows a web
server supplying a cookie to a client to specify a subset of URLs on
the origin server to which the cookie applies.  Web servers such as
Apache do not filter returned cookies and assume that the client will
only send back cookies for requests which fall within the
server-supplied subset of URLs. However, by supplying URLs which use
path traversal (/../) and character encoding, it is possible to fool
many browsers into sending a cookie to a path outside of the
originally specified subset.

KDE version 3.1.3 and later include a patch to Konquerer that disables
the sending of cookies to the server if the URL contains such encoded
traversals.  Red Hat Enterprise Linux 2.1 shipped with KDE 2.2.2 and
therefore is vulnerable to this issue.
