Summary

Details

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 CCreateObject, nor when CDeriveKey is used with ECDH public data. This may allow a malicious user to extract the private key by performing an invalid curve attack.
