Abstract
IMMEDIATE ACTION REQUIRED if REXX execs downloaded from z/OS Tools and Toys site between 6 January 2021 and 19 October 2022
Content
The REXX execs on z/OS Tools and Toys were updated on 6 January 2021 to include license text within the header. An extraneous '*' was added between the '/' and 'REXX' keyword on the first line of the REXX execs, as follows:
/** REXX **************************************************************
The extra '*' causes these sample REXX execs to recursively spawn new processes when executed from the OMVS shell under a superuser (UID 0 user), which might result in a system outage due to the exhaustion of system address spaces (MAXUSER parameter in IEASYSxx parmlib member). All of these REXX execs on z/OS Tools and Toys were updated on 18 October 2022 to remove the extraneous '*'.
Immediate action is required if any REXX execs were downloaded from the z/OS Tools and Toys site between 6 January 2021 and 19 October 2022. Remove the download REXX execs from the system, and redownload from z/OS Tools and Toys. Once redownloaded, verify that the first line of the REXX exec contains only one '*' between the '/' and 'REXX' keyword, as follows:
/* REXX **************************************************************
