Fedora 34: FEDORA-2021-33f8ebd09c Critical: OpenCryptoki Key Security

When constructing an OpenSSL EC public or private key from PKCS#11 attributes or ECDH public data, check that the key is valid, i.e. that the point is on the curve. This prevents one from creating an EC key object via C_CreateObject with invalid key data. It also prevents C_DeriveKey to derive a secret using ECDH with an EC public key (public data) that uses a different curve or is invalid by. --------------------------------------------------------------------------------Fedora Update Notification FEDORA-2021-33f8ebd09c 2021-09-02 23:45:36.565238 --------------------------------------------------------------------------------Name : opencryptoki Product : Fedora 34 Version : 3.16.0 Release : 2.fc34 URL : https://github.com/opencryptoki/opencryptoki Summary : Implementation of the PKCS#11 (Cryptoki) specification v2.11 Description : Opencryptoki implements the PKCS#11 specification v2.11 for a set of cryptographic hardware, such as IBM 4764 and 4765 crypto cards, and the Trusted Platform Module (TPM) chip. Opencryptoki also brings a software token implementation that can be used without any cryptographic hardware. This package contains the Slot Daemon (pkcsslotd) and general utilities. --------------------------------------------------------------------------------Update Information: When constructing an OpenSSL EC public or private key from PKCS#11 attributes or ECDH public data, check that the key is valid, i.e. that the point is on the curve. This prevents one from creating an EC key object via C_CreateObject with invalid key data. It also prevents C_DeriveKey to derive a secret using ECDH with an EC public key (public data) that uses a different curve or is invalid by other means. The problem is fixed in opencryptoki-3.16.0-2 --------------------------------------------------------------------------------ChangeLog: * Tue Aug 24 2021 Than Ngo - 3.16.0-2 - Fixed bz#1990592, allows invalid curve attacks via a specially craftedkey --------------------------------------------------------------------------------References: [ 1 ] Bug #1990591 - opencryptoki: allows invalid curve attacks via a specially crafted key https://bugzilla.redhat.com/show_bug.cgi?id=1990591 --------------------------------------------------------------------------------This update can be installed with the "dnf" update program. Use su -c 'dnf upgrade --advisory FEDORA-2021-33f8ebd09c' at the command line.
