Affected packages
• PyPI openssh-key-parser: < 0.0.6 → fixed in 0.0.6
Description
Impact
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.
Patches
Upgrade to version 0.0.6, which no longer includes the raw field value in the error message.
