Mandrake Linux Security Advisory : kdebase (MDKSA-2003:091)

critical Nessus Plugin ID 14073

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

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.

Solution

Update the affected packages.
