KDE Security Advisory: Buffer overflow in fliccd of kdeedu/kstars/indi
Original Release Date: 2005-02-15
URL: http://www.kde.org/info/security/advisory-20050215-1.txt

1. Systems affected:

        KDE 3.3 up to including KDE 3.3.2.


2. Overview:

        KStars includes support for the Instrument Neutral Distributed
        Interface (INDI). The build system of this extra 3rd party
        software contained an installation hook to install fliccd (part
        of INDI) as SUID root application. 

        Erik Sjölund discovered that the code contains several
        vulnerabilities that allow stack based buffer overflows.


3. Impact:

        If the fliccd binary is installed as suid root, it enables root
        privilege escalation for local users, or, if the daemon is
        actually running (which it does not by default) and is running
        as root, remote root privilege escalation.


4. Solution:

        Source code patches have been made available which fix these
        vulnerabilities. Contact your OS vendor / binary package provider
        for information about how to obtain updated binary packages.


5. Patch:

        A patch for 3.3.2 is available from 
        ftp://ftp.kde.org/pub/kde/security_patches :
