Oracle issued a critical patch update this week which provided 254 security fixes, including patches for the Spectre (CVE-2017-5753, CVE-2017-5715) and Meltdown (CVE-2017-5754) vulnerabilities. These fixes apply across much of the Oracle product family. A complete list of products this update applies to is listed in the Oracle advisory.
It is recommended that organizations using such products patch the systems as soon as possible. Failure to do so could leave your organization unnecessarily vulnerable to critical attacks and data exploitation.
