Oracle has released 101 new patches to address vulnerabilities across its entire range of products.

Among the vulnerabilities listed are 63 fixes that address flaws in Oracle's database products, 14 aimed at plugging holes in the company's application server products, 13 for vulnerabilities in its e-business suites and nine patches addressing security flaws in the company's PeopleSoft and JD Edwards software.

"More than one-third of the vulnerabilities patched in this [critical patch update] are in an optional product and do not affect most customers" a post on Oracle's security blog noted. "It is also worth noting that 22 of the vulnerabilities addressed in this CPU affect Oracle Database, but none of these vulnerabilities impact Oracle Database Client," the blog post said.

As with Oracle's previous security updates, all of these patches, with the exception of those for its ebusiness suite, are cumulative, according to the blog. Thus, a customer that implements Tuesday's patches will automatically be protected against all flaws announced Tuesday as well as those covered in previous security updates, the company added.

The patches are part of Oracle's scheduled quarterly critical patch updates. The last one was in July.

For the first time since moving to a quarterly patch-release schedule in November 2004, Oracle included new documentation with its latest critical patch update. Among the new information is an executive summary that gives a high-level overview of the vulnerabilities addressed with the latest patches. Also included is a vulnerability rating system based on the Common Vulnerability Scoring System (CVSS), which is an emerging standard for rating security flaws. The changes have been introduced in response to customer requests to make Oracle's patching process a little easier to understand.

A total of 45 flaws were listed as being remotely exploitable without requiring authentication by the attackers. Such flaws were highlighted for the first time in Oracle's critical patch updates as part of the company's effort to give customers more vulnerability-related information.

The company has come a "long way" in its patching processes, said Rich Niemiec, a former president of the International Oracle Users Group and the CEO of The Ultimate Software Consultants, an Oracle technology consulting firm. The increased documentation that Oracle started making available with this update also makes it easier for customers to identify relevant patches and "calculate the resources that will be required" to implement the fixes, he said.
