                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           kdebase
Advisory ID:            MDKSA-2003:091
Date:                   September 16th, 2003

Affected versions:      9.0, 9.1, Corporate Server 2.1
________________________________________________________________________

Problem Description:

 A vulnerability was discovered in all versions of KDE 2.2.0 up to and
 including 3.1.3.  KDM does not check for successful completion of the
 pam_setcred() call and in the case of error conditions in the installed
 PAM modules, KDM may grant local root access to any user with valid
 login credentials.  It has been reported to the KDE team that a certain
 configuration of the MIT pam_krb5 module can result in a failing
 pam_setcred() call which leaves the session alive and would provide root
 access to any regular user.  It is also possible that this vulnerability
 can likewise be exploited with other PAM modules in a similar manner.
 
 Another vulnerability was discovered in kdm where the cookie session
 generating algorithm was considered too weak to supply a full 128 bits
 of entropy.  This allowed unauthorized users to brute-force the session
 cookie.
 
 mdkkdm, a specialized version of kdm, is likewise vulnerable to these
 problems and has been patched as well.
