  IBM Tivoli Management Framework Buffer Overflow (ManagedNode)
------------------------------------------------------------------------

SUMMARY

A remote buffer overflow condition exists in the web server (default port
94 but redirects to another port) running on TMR ManagedNodes. This
results in a denial of service and the possibility of arbitrary code
execution.

DETAILS

Vulnerable systems:
 * IBM Tivoli version 3.6.x through 3.7.1

Immune systems:
 * IBM Tivoli version 4.1

An overly long GET request results in a buffer overflow, with registers
being overwritten with user supplied data.

This results in the TMR ManagedNode HTTPd daemon crashing (Spider process)
and allows arbitrary code to be executed as a privileged user (SYSTEM on
NT or root on UNIX). The loss of the spider process will prevent all HTTP
requests to that ManagedNode, but does not affect all other Framework or
application functions.

Fix:
Apply workaround.

Vendor status:
Tivoli were notified 12 April 2002.

Vendor has released a security alert with details of patches and
workarounds. See
