✅ Remediation

Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 Workaround: It is not a very straight forward workaround but it is possible to mitigate this by manually editing the default Email ID ([email protected]) to some valid email ID ([email protected]) in the USER_ENTITY table in the RHSSO database used. Workaround: This flaw only affects the Security Manager running under JDK 11 or 8. To mitigate exposure to this flaw, do not run under those JDK versions.
