Acrobat Reader 2017 Clasis crash post Jan 2022 security RDRcef.exe

[Shoggi1105]

Dear Support,

we were running Acrobat Reader 2017 Enteprise without issues.

Since we deployed the Jan 2022 update 17.011.30207 we have constantly crashes and now in 7 days or 54.000 instances.

We had something similar in the past and it was a bug. Is this know or anything related to the latest update?

Regards

Lukas
