                Mandrake Linux Security Update Advisory

Package name:           kdelibs
Advisory ID:            MDKSA-2002:079
Date:                   November 21st, 2002

Affected versions:      9.0

Problem Description:

 Vulnerabilities were discovered in the KIO subsystem support for various
 network protocols.  The implementation of the rlogin protocol affects
 all KDE versions from 2.1 up to 3.0.4, while the flawed implementation
 of the telnet protocol only affects KDE 2.x.  They allow a carefully
 crafted URL in an HTML page, HTML email, or other KIO-enabled application
 to execute arbitrary commands as the victim with their privilege.
 The KDE team provided a patch for KDE3 which has been applied in these
 packages.  No patch was provided for KDE2, however the KDE team 
 recommends disabling both the rlogin and telnet KIO protocols.  This
 can be accomplished by removing, as root, the following files:
 /usr/share/services/telnet.protocol and 
 /usr/share/services/rlogin.protocol.  If either file also exists in a
 user's ~/.kde/share/services directory, they should likewise be removed.
