Summary
Red Hat Security Advisory: : Updated gnupg packages fix validation bug
Severity
Moderate
Notes
Topic: Updated gnupg packages correcting a bug in the GnuPG key validation functions are now available.
Details: The GNU Privacy Guard (GnuPG) is a utility for encrypting data and creating digital signatures. When evaluating trust values for different UIDs assigned to a given key, GnuPG versions earlier than 1.2.2 would incorrectly associate the trust value of the UID with the highest trust value with every UID assigned to that key. This would prevent an expected warning message from being generated. All users are advised to upgrade to these errata packages which include patches from the GnuPG development team that correct this issue for GnuPG versions 1.0.7 and 1.2.1. This update also upgrades Red Hat Linux 7.1, 7.2, and 7.3 users to GnuPG version 1.0.7.

CVE-2003-0255

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.
