An issue was discovered in Rclone before 1.53.3. Due to the use of a weak random number generator, the password generator has been producing weak passwords with much less entropy than advertised. The suggested passwords depend deterministically on the time the second rclone was started. This limits the entropy of the passwords enormously. These passwords are often used in the crypt backend for encryption of data. It would be possible to make a dictionary of all possible passwords with about 38 million entries per password length. This would make decryption of secret material possible with a plausible amount of effort. NOTE: all passwords generated by affected versions should be changed.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

    password length. This would make decryption of secret material possible with a plausible amount of effort.
    NOTE: all passwords generated by affected versions should be changed. (CVE-2020-28924)

The remote host is affected by the vulnerability described in GLSA-202107-14 (rclone: Weak random number generation)

    Passwords generated with rclone were insecurely generated and are       vulnerable to brute-force attacks.
  Impact :

    Data kept secret with a password generated by rclone may be disclosed to       a local attacker.
  Workaround :

    There is no known workaround at this time.
