Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Siemens/RUGGEDCOM RST2428P.
  2. 2Review the reported fix. Update Linux/Linux to 67b9a278b80f71ec62091ded97c6bcbea33b5ec3; Siemens/RUGGEDCOM RST2428P to V3.2; Siemens/SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family to V3.2; Siemens/SCALANCE XCM-/XRM-/XCH-/XRH-300 family to V3.2; Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP to V3.1.5; Siemens/SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP to V3.1.5; Siemens/SIMATIC S7-1500 TM MFP - GNU/Linux subsystem to *; Siemens/SIMATIC S7-1500 TM MFP - GNU/Linux subsystem to V1.1.1; Siemens/SIPLUS S7-1500 CPU 1518-4 PN/DP MFP to V3.1.5 if you use the affected versions. Test the change in a non-production environment first.
