KDE Security Advisory: kpf Directory traversal
by Nikola Strahija on October 12th, 2002 1. Systems affected: kpf of any KDE release between KDE 3.0.1 and KDE 3.0.3a.
2. Overview:
kpf is a file sharing utility that can be docked into the
KDE kicker bar. It uses a subset of the HTTP protocol internally
and acts much similiar to a webserver.
A feature added in KDE 3.0.1 accidently allowed retrieving any
file, not limited to the configured shared directory, if it is
readable by the user kpf runs under.
3. Impact:
Files not stored in the shared directory were remotely
retrievable.
4. Solution:
The vulnerable feature has been removed.
Apply the patch listed in section 5 to kdenetwork/kpf, or update
to KDE 3.0.4.
kdenetwork-3.0.4 can be downloaded from
http://download.kde.org/stable/3.0.4 :
9f64e76cc6b922e1bf105099e3bf8205 kdenetwork-3.0.4.tar.bz2
5. Patch:
A patch for KDE 3.0.3 is available from
ftp://ftp.kde.org/pub/kde/security_patches :
