Vulnerability from github – Published: 2022-07-06 19:24 – Updated: 2024-10-07 21:17
VLAI?
Summary
Possible leak of key's raw field if declared length is incorrect
Details

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
