Mandrake alert: Updated XFree86 packages fix xdm vulnerability
|
|
A vulnerability was discovered in the XDM display manager that ships with XFree86. XDM does not check for successful completion of the pam_setcred() call and in the case of error conditions in the installed PAM modules, XDM may grant local root access to any user with valid login credentials. It has been reported 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.

Mandrake Linux Security Update Advisory
_______________________________________________________________________
Package name: XFree86
Advisory ID: MDKSA-2003:118
Date: December 19th, 2003
Affected versions: 9.0, 9.1, 9.2, Corporate Server 2.1

Problem Description:
A vulnerability was discovered in the XDM display manager that ships
with XFree86. XDM does not check for successful completion of the
pam_setcred() call and in the case of error conditions in the
installed PAM modules, XDM may grant local root access to any user
with valid login credentials. It has been reported 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.
A backported patch from XFree86 4.3 that corrects this vulnerability
has been applied to these updated packages.
