Package Vulnerable versions Unaffected versions Architecture(s)

KDE is vulnerable to a local Denial of Service attack.

2.  Impact Information


KDE is a feature-rich graphical desktop environment for Linux and Unix-like Operating Systems. DCOP is KDE's simple IPC/RPC mechanism.


Sebastian Krahmer discovered that it is possible to stall the dcopserver of other users.


An attacker could exploit this to cause a local Denial of Service by stalling the dcopserver in the authentication process. As a result all desktop functionality relying on DCOP will cease to function.

3.  Resolution Information


There is no known workaround at this time.


All kdelibs users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose kde-base/kdelibs
