Oracle is due to release 59 fixes for critical vulnerabilities as part of its quarterly patch cycle.
The company said in a pre-release announcement that customers should apply its Critical Patch Update, which contains the fixes, as soon as possible. The update will become available on Tuesday from Oracle's Critical Patch Update website.
The Critical Patch Update addresses vulnerabilities across many Oracle products, although 21 of the 59 holes are in the Solaris product suite, said the company.
Affected Oracle Solaris Suite products include Access Manager, OpenSSO, Solaris and Solaris Studio. Other affected products include Oracle Database, Oracle Identity Management and Oracle WebLogic Server.
Oracle released a patch in April 2010, with fixes for 47 vulnerabilities.
