IBM Tivoli Management Framework Buffer Overflow (ManagedNode)
Announcement date: 15th July 2002
Product: IBM Tivoli Management Framework
Vulnerable versions: 3.6.x through 3.7.1
Vulnerability Type : Buffer Overflow
Vendor-Status: A fix is forthcoming in Version 4.1. A workaround is
available for earlier versions.
A remote buffer overflow condition exists in the webserver (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
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 impact all
other Framework or application functions.
Tested on: Solaris8 (Sparc).
