Summary:  
EMC ResourcePak Base contains a fix for a privilege management  vulnerability that could potentially be exploited by malicious users to compromise the affected system. 

Details:  
EMC Mainframe Enablers ResourcePak Base versions  7.6.0, 8.0.0 and 8.1.0 allows a Key 8 program to run in supervisor state instead of  problem state.  This could allow the program code which runs as an authorized user to give control to another Key 8 program in supervisor state.  Supervisor state can allow privileged instructions to execute and/or cause inadvertent or intentional storage overlays which could lead to data corruption.

The following EMC Mainframe Enablers ResourcePak Base (EMCSCF) release contains resolutions to this vulnerability:

  EMC EMCSCF 7.6.0  version with fix SF76150
