Oracle has issued 65 fixes for a wide range of software products as part of its quarterly security release, called the Critical Patch Update.

The patches, released Tuesday, address problems in the company's database, application server, and e-business suite products, among others, according to Darius Wiles, manager of Oracle Security Alerts. More information on the patches can be found here.

Some of the patches are also designed for client software that works with Oracle's databases, he said. "There are 23 fixes for vulnerabilities that affect database servers and another four that apply to clients."

Included in the patches are fixes for an exploit that had been made public on the Bugtraq mailing list back in April, as well as a fix for a bug that Oracle had inadvertently disclosed on (and then quickly removed from) its own Metalink support service. The Bugtraq exploit can be found here.

Oracle has released 10 fixes for its Application Server and 20 fixes for its E-Business Suite, Wiles said.

Many of the vulnerabilities relate to a proprietary networking protocol used by Oracle's database, called Oracle Net. This protocol has come under increased scrutiny over the past year, according to Amichai Shulman, chief technology officer with Imperva Inc.

"No one has explored these options up until now," Shulman said. "Once people dive into these obscure protocols, they are sure to find many vulnerabilities."

Often network vulnerabilities can be the most dangerous, he said, "because you don't need any database credentials in order to exploit them."

Oracle's next critical patch update is scheduled for Oct. 17.
