GHSA-hm37-9xh2-q499
Possible leak of key's raw field if declared length is incorrect
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | openssh-key-parser | < 0.0.6 | 0.0.6 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
### Workarounds
N/A
