Quick fix
PYSEC-2022-233 — openssh-key-parser: upgrade to the fixed version with the command below.
pip install --upgrade 'openssh-key-parser>=d5b53b4b7e76c5b666fc657019dbf864fb04076c'Details
openssh_key_parser is an open source Python package providing utilities to parse and pack OpenSSH private and public key files. In versions prior to 0.0.6 if a field of a key is shorter than it is declared to be, the parser raises an error with a message containing the raw field value. An attacker able to modify the declared length of a key's sensitive field can thus expose the raw value of that field. Users are advised to upgrade to version 0.0.6, which no longer includes the raw field value in the error message. There are no known workarounds for this issue.
