Description

The default lifetime on internal CRLs is 9999 which as of now lands the expiration of a CRL past 2050. The CRL library uses a UTCTime string for dates which has a 2-digit year and 2050 dates, shortened to 50, are rolled back to 1950.

Reducing the default lifetime of internal CRLs is safe as they are regenerated as needed not manually, they would rarely approach any CRL expiration date as any time a CRL consumer service restarts it refreshes the CRL contents and gets a fresh expiration date.

2 years (730 days) should be more than sufficient.

Also the backend code should reduce the maximum allowed CRL lifetime so it doesn't cross that time barrier.

This is affecting production systems using CRLs so any fix should also be added to the system patches package so affected users can apply the fix ASAP.
