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.
