You should verify applying this fix does not cause any compatibility issues. The fix disables MD5 signature hash by default. If you change the default setting after applying the fix, you will expose yourself to the attack described above. IBM recommends that you review your entire environment to identify other areas where you have enabled the MD5 signature hash and take appropriate mitigation and remediation actions.
