Yesterday, Oracle released their quarterly updates.
http://www.oracle.com/technology/deploy/security/critical-patch-updates/cpuoct2006.html

David Litchfield released an excellent summary here:
http://www.databasesecurity.com/oracle/OracleOct2006-CPU-Analysis.pdf

There are too many updates (101) to go into much detail (or fully digest to be honest) here.
It is worth noting that there are gaps in coverage in the update.
From David's report:

Version	Platform	Due
9.2.0.6	All Operating Systems	End of Oct.
10.1.0.5	All Operating Systems	End of Oct.
10.2.0.1	Linux (Power)	End of Oct.
10.2.0.2	Windows	End of Oct.

The tools from Oracle, NGSSoftware and others for evaluating risk matrices based upon the Oracle applications, versions, and platforms in use highlights the complexity of determining exposure points. Its probably a good idea to use this strategy across all the applications and platforms in your environment and there are a number of tools to do this. And all of these techniques require a good system inventory which is kept up to date with the platforms and services installed in a network. Everyone keeps and maintains those too right?

It is also worth noting that Oracle has adopted the Common Vulnerability Scoring System (CVSS).

Additional summary details from the SC Magazine article (thanks to a certain person that sends out the highest number of news digests ever)
"The update delivered fixes for a host of company solutions, including
Oracle Database (22 patches), Application Server (14), E-Business Suite
(13) and PeopleSoft Enterprise (eight).

None of the bugs in Oracle Database - the vendor's most popular product
- are remotely exploitable without valid authorization, according to
the CPU. The highest Database risk assessment score - on a scale of 1
to 10 - was 4.2."
