v1.5.4 Release Notes - June 17, 2022 | ||
==================================== | ||
|
||
Release v1.5.4 updates Fabric CA to use https://github.com/IBM/idemix for the Identity Mixer implementation, | ||
making it possible to issue credentials using various Identity Mixer curves. | ||
The Identity Mixer curve can be configured in the Fabric CA server and client configuration yaml file: | ||
|
||
``` | ||
# Specifies the Elliptic Curve used by Identity Mixer. | ||
# It can be any of: {"amcl.Fp256bn", "gurvy.Bn254", "amcl.Fp256Miraclbn"}. | ||
# If unspecified, it defaults to 'amcl.Fp256bn'. | ||
curve: amcl.Fp256bn | ||
``` | ||
|
||
Dependencies | ||
------------ | ||
|
||
Fabric CA v1.5.4 has been tested with the following dependencies: | ||
- Go 1.18.2 | ||
- Alpine 3.16 (for Docker images) | ||
|
||
|
||
Changes, Known Issues, and Workarounds | ||
-------------------------------------- | ||
None. | ||
|
||
Known Vulnerabilities | ||
--------------------- | ||
- FABC-174 Commands can be manipulated to delete identities or affiliations | ||
|
||
This vulnerability can be resolved in one of two ways: | ||
|
||
1) Use HTTPS (TLS) so that the authorization header is not in clear text. | ||
|
||
2) The token generation/authentication mechanism was improved to optionally prevent | ||
token reuse. As of v1.4 a more secure token can be used by setting environment variable: | ||
|
||
FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false | ||
|
||
However, it cannot be set to false until all clients have | ||
been updated to generate the more secure token and tolerate | ||
FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false. | ||
The Fabric CA client has been updated in v1.4 to generate the more secure token. | ||
The Fabric SDKs will be updated by v2.0 timeframe to generate the more secure token, | ||
at which time the default for Fabric CA server will change to: | ||
FABRIC_CA_SERVER_COMPATIBILITY_MODE_V1_3=false | ||
|
||
Resolved Vulnerabilities | ||
------------------------ | ||
None. |
