KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. KStars is a desktop planetarium for KDE. It includes support for the Instrument Neutral Distributed Interface (INDI).
Erik Sjolund discovered a buffer overflow in fliccd which is part of the INDI support in KStars.
An attacker could exploit this vulnerability to execute code with elevated privileges. If fliccd does not run as daemon remote exploitation of this vulnerability is not possible. KDE as shipped by Gentoo does not start the daemon in the default installation.
There is no known workaround at this time.
All KStars users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdeedu-3.3.2-r1"
