Additional fixes are under development and will be made available for the remaining platforms (Linux, iOS, and Android).\n\nThe fix for this vulnerability requires three steps:\n * Ensure that all of your GlobalProtect portals use TLS certificate chains that meet the criteria specified in the \"FIPS-CC Certification Validation\" table in our documentation https://docs.paloaltonetworks.com/globalprotect/10-1/globalprotect-admin/certifications/resolve-fips-cc-mode-issues .\n * Ensure that the TLS certificate chains used by the GlobalProtect portals are added to the root certificate store in your operating system.\n * Install a fixed version of GlobalProtect using one of the deployment options below. This setting enforces strict X.509v3 verification checks on the certificate provided by the GlobalProtect portal.\n\nNote: Prisma Access customers using portals with a *.gpcloudservice.com domain name already have valid TLS certificate chains. The root certificate for these portals is from GoDaddy, which is trusted by default in Windows, macOS, RHEL, Ubuntu, iOS, and Android. Therefore, Prisma Access customers using a GlobalProtect portal with a *.gpcloudservice.com domain name should only need to perform step 3 above.\n\nImportant: If your GlobalProtect portals do not use valid X.509V3 TLS certificate chains, this will result in TLS verification failures.

This is due to certificate providers that rate limit requests for Online Certificate Status Protocol (OCSP) and certificate revocation list (CRL) checks.
