Severity
Important
Notes
Title of the patch: Security update for cryptctl
Description of the patch: This update for cryptctl fixes the following issues:
Update to version 2.4:
- CVE-2019-18906: Client side password hashing was equivalent to clear text password storage (bsc#1186226)
- First step to use plain text password instead of hashed password.
- Move repository into the SUSE github organization
- in RPC server, if client comes from localhost, remember its ipv4 localhost address instead of ipv6 address
- tell a record to clear expired pending commands upon saving a command result; introduce pending commands RPC test case
- avoid hard coding 127.0.0.1 in host ID of alive message test; let system administrator mount and unmount disks by issuing these two commands on key server.
