CVE-2006-0550: Buffer overflow in an unspecified Oracle Client utility might allow remote attackers to execute arbitrary code or cause a denial of service.

Buffer overflow in an unspecified Oracle Client utility might allow remote attackers to execute arbitrary code or cause a denial of service.

Buffer overflow in an unspecified Oracle Client utility might allow remote attackers to execute arbitrary code or cause a denial of service. NOTE: due to the lack of relevant details from the Oracle advisory, a separate CVE is being created since it cannot be conclusively proven that this issue has been addressed by Oracle. It is possible that this is the same issue as Oracle Vuln# DBC02 from the January 2006 CPU, in which case this would be a duplicate of CVE-2006-0283. However, there are enough inconsistencies that the mapping can not be made authoritatively.

Description from the National Vulnerability Database, published by MITRE

What it means for a small business

If your business uses Oracle Client, install the vendor's update. If you're not sure whether you use it, ask whoever manages your computers.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 8.2%, top 5% of all CVEs. That’s above average: worth scheduling this week. Scored November 6, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
