CVE Catalog

CVE-2003-0255

High
Published: Translated: NVD NIST

Summary

The key validation code in GnuPG before version 1.2.2 improperly assesses the validity of keys with multiple user IDs, assigning the highest validity to the most valid user ID. This prevents GnuPG from warning the encrypting user when a user ID lacks a trusted path.

Risk Assessment

The organization may be at risk of using incorrect encryption keys, potentially leading to data confidentiality loss. The lack of warnings about untrusted user IDs increases the risk of unauthorized access to information.

Recommendation

It is recommended to update GnuPG to version 1.2.2 or later to improve key validation. Additionally, conducting an audit of user keys to ensure their trustworthiness is advisable.

Original NVD description (English source)

The key validation code in GnuPG before 1.2.2 does not properly determine the validity of keys with multiple user IDs and assigns the greatest validity of the most valid user ID, which prevents GnuPG from warning the encrypting user when a user ID does not have a trusted path.
