Detailsinfo

A vulnerability was found in openssh_key_parser up to 0.0.5 on Python (Connectivity Software). It has been classified as problematic. This affects some unknown functionality. The manipulation with an unknown input leads to a information exposure vulnerability. CWE is classifying the issue as CWE-209. The product generates an error message that includes sensitive information about its environment, users, or associated data. This is going to have an impact on confidentiality. The summary by CVE is:

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.
