Ian - I haven't been able to locate this on Metalink, but can you give a
quick idea about how I can ensure I don't have a vulnerability here? Our
databases are behind firewalls and all access is through app servers.
Thanks.

The exploit  involves passing a large argv[1] argument to  the oracle or
oracle0 binary.   Credit for discovering the vulnerability goes to
[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> .  The error was first
discovered on a LINUX box but I have seen notes that AIX is vulnerable as
well.  What is not published in North America yet, is the Oracle alert you
mention.  The first security note I saw on this was published  on 19
October.   Yes  there are people who know how to exploit the  vulnerability.
The vulnerability was shown to Oracle  over a month ago, according to the
comments in a proof of concept exploit.
 
One workaround is to take off the setuid bit from the Oracle binary    Is it
really necessary to set this.  How many places  still have  users log into
the database server?    Oracle has recommended putting its databases behind
firewalls for some time.

Important:  Please read the following Oracle Alert.

We strongly recommend that you do not connect the Oracle Database
directly to the Internet.

Got your attention?  That is what is in the Alert.  These alerts are
beginning 
to come all too often.  Sounds just like Microsoft's software, yeah?

Buffer Overflow in Oracle Database Server Binaries
This is with the Oracle kernel/binary itself ie 'oracle' or 'oracleO' file
in $ORACLE_HOME/bin.


Description
A potential buffer overflow has been discovered in the "oracle" and
"oracleO" (the letter O) binaries
of the Oracle Database. A knowledgeable and malicious local user can exploit
this buffer overflow
to execute code on the operating system hosting the Oracle Database server.
Products Affected
* Oracle 9i Database Release 2, Version 9.2.x
* Oracle 9i Database Release 1, Version 9.0.x
Platforms Affected
All supported UNIX and Linux operating system variants.


Patch only available for Linux right now.  

So who found out this vulnerability? David Litchfield? Aaron Newman?
I know it is a bit silly to ask but does anyone know how 
to exploit this vulnerability?  Send it to me directly if you dont want to 
reply publicly
