Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

Multiple vulnerabilities in start_kdeinit could possibly allow a local
attacker to execute arbitrary code with root privileges.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

KDE is a feature-rich graphical desktop environment for Linux and
Unix-like operating systems. start_kdeinit is a wrapper for kdeinit.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

     -------------------------------------------------------------------

                                                           *>=3D 3.5.9-r3=

                                                                  > 4.0
                                                                < 3.5.5

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Vulnerabilities have been reported in the processing of user-controlled
data by start_kdeinit, which is setuid root by default.

Impact
=3D=3D=3D=3D=3D=3D

A local attacker could possibly execute arbitrary code with root
privileges, cause a Denial of Service or send Unix signals to other
processes, when start_kdeinit is setuid root.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All kdelibs users should upgrade to the latest version:

     # emerge --sync
     # emerge --ask --oneshot --verbose ">=3Dkde-base/kdelibs-3.5.8-r4"
