==========================================================
Various bugs in Samba's NDR parsing can allow a user
to send specially crafted MS-RPC requests that will
overwrite the heap space with user defined data.
A patch against Samba 3.0.24 has been posted at
http://www.samba.org/samba/security/
There is no immediate workaround for this defect that does
not involve changing the server code in the smbd daemon.
The Samba Team always encourages users to run the latest
stable release as a defense against attacks. If this
is not immediately possible, administrators should read
the "Server Security" documentation found at
http://www.samba.org/samba/docs/server_security.html
This vulnerability was reported to Samba developers by Brian
Schafer, TippingPoint Security Response Lead, as part
of the Zero Day Initiative (http://www.zerodayinitiative.com).
