Description
When a vendor drops support of System Software, they no longer maintain security vulnerability patches to the software. Without vulnerability patches, it is impossible to verify that the system does not contain code which could violate the integrity of the operating system environment. To be eligible to be included for this vulnerability, the product must meet the following criteria: - Uses authorized and restricted z/OS interfaces by utilizing Authorized Program Facility (APF) authorized modules or libraries. - Require access to system datasets or sensitive information or requires special or privileged authority to run.

Fix Text (F-27142r1_fix)
The IAO will ensure that unsupported system software is removed or upgraded prior to a vendor dropping support. Update the software and products listed in the Supported Software Version Release Table in the z/OS STIG Addendum to a supported or later version. And update any APF Autorized products running at your site and not included in the table to an owning vendors supported version. Authorized software which is NO longer supported is CAT I - The customer and site will be given 6 months to mitigate the risk, come up with a supported solution or obtain a formal letter approving such risk/software.
