GLSA 200503-22: KDE: Local Denial of Service

http://security.gentoo.org/

Severity:	normal
Title:	KDE: Local Denial of Service
Date:	03/19/2005
Bugs:	#83814
ID:	200503-22

Synopsis

KDE is vulnerable to a local Denial of Service attack.

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
kde-base/kdelibs	< 3.3.2-r7	>= 3.3.2-r7	All supported architectures

Description

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

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All kdelibs users should upgrade to the latest version:

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