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
KDE 3.3 up to including KDE 3.3.2.
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.
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.
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.
A patch for 3.3.2 is available from ftp://ftp.kde.org/pub/kde/security_patches : 2b9c8330bec2c0dc6669ccc40b24dd70 post-3.3.2-kdeedu-kstars.diff
