NVD Description

Note: Versions mentioned in the description apply only to the upstream opencryptoki-ccatok package and not the opencryptoki-ccatok package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw was found in openCryptoki. The openCryptoki Soft token does not check if an EC key is valid when an EC key is created via C_CreateObject, nor when C_DeriveKey is used with ECDH public data. This may allow a malicious user to extract the private key by performing an invalid curve attack.
