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. References

  2. Systems affected:

    KDE 3.3 up to including KDE 3.3.2.
  3. 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.
  4. 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.
  5. 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.
  6. Patch:

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