CVE-2022-31124
An attacker able to modify the declared length of a key's sensitive field can thus expose the raw value of that field.
Does this matter?
Lower severity and a low EPSS score (1.30%). Track it; it rarely justifies an emergency change on its own.
Description
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.
