Study: Oracle database has more flaws than SQL Server

A comparison of Microsoft's SQL Server database and Oracle's relational database management (RDBM) shows Oracle's products to have far more vulnerabilities

Microsoft may be taking the most heat among software vendors for security problems but it's not always the one with the worst record.

A comparison of vulnerabilities in Microsoft's SQL Server database and Oracle's relational database management (RDBM) products by UK-based Next Generation Security Software (NGSS) shows Oracle's products to have far more vulnerabilities than do products from Microsoft.

Between December 2000 and November 2006, external researchers discovered 233 vulnerabilities in Oracle's products compared to 59 in Microsoft's SQL Server technology, according to NGSS. The study looked at vulnerabilities that were reported and fixed in SQL Server 7, 2000 and 2005 and Oracle's database versions 8, 9, and 10g.

The results showed that the reputation for relatively poor security that MS SQL server had back in 2002 was no longer deserved, founder of NGSS, David Litchfield, said. And neither was the beating that Microsoft has received for security issues, he said.

"I think it's time people got past this, especially security researchers," Litchfield said. "We should be about closing holes and improving a vendor's outlook on security and -- largely -- that battle has been won with Microsoft," he said. The results show that Microsoft's software development lifecycle processes appear to be working, he said.

"There are other battles needing to be fought and won -- Oracle being one of them," he said.

In an emailed comment, an Oracle spokeswoman said the number of reported vulnerabilities in a product alone was not a measure of the overall security of that software.

"Products vary significantly in terms of richness of features and capabilities as well as number of versions and supported platforms," she said. "Measuring security is a very complex process, and customers must take a number of factors into consideration -- including use case scenarios, default configurations as well as vulnerability remediation and disclosure policies and practices."

Basing a product's security just on the number of vulnerabilities discovered and fixed might not be the best approach, an analyst with Burton Group, Pete Lindstrom, said.

"Oracle apparently won an ugly contest," he said.

But there's had to be other criteria other than known vulnerabilities for measuring software security, Lindstrom. Until then, the jury should still be out on what was more or less secure.

The NGSS report comes at a time when security researchers, irked by what they consider to be Oracle's glacial pace of fixing bugs, are increasingly turning their attention to its products. In October, the company announced fixes for more than 100 flaws as part of its scheduled quarterly security updates. Many of the flaws were reported to the company by outside researchers.

Just last week, Argeniss Information Security in Buenos Aires announced plans to disclose one zero-day bug every day for a week in December.

In a note posted on the company's site, founder, Cesar Cerrudo, said the idea was to highlight the current state of Oracle software security. "We want to demonstrate that Oracle isn't getting any better at securing its products," and continues to take a very long time to address bugs, the note said. "We could do the Year of Oracle Database Bugs but we think a week is enough to show how flawed Oracle software is."
