Oracle Corp. is warning customers to apply software patches it released in August, citing the availability of malicious code that can exploit unpatched vulnerabilities in its software.

The company acknowledged in a recent security alert describing the vulnerabilities that it has received notification that there are published exploits for “some of the issues” addressed in the alert. The company did not provide information about the exploits.

Oracle did not immediately respond to a request for comment on the reported exploits.

The security holes affect a number of Oracle products, including versions of its 8i, 9i and 10g Database, Application Server and Enterprise Manager software, according to a bulletin posted by Oracle on Aug. 31, which also released a patch for the vulnerabilities.
