[openssl-dev] [openssl.org #3975] The CMS encrypt command uses the wrong ASN.1 encoding for the AES-GCM algorithm parameter.

[Stephen Henson via RT]

GCM mode isn't currently supported in CMS, it was a bug that it attempted to
use it and produced incorrect results. Resolved now to return an error for GCM.
