Mandrake Linux Security Advisory : gnupg (MDKSA-2003:061)

A bug was discovered in GnuPG versions 1.2.1 and earlier. When gpg evaluates trust values for different UIDs assigned to a key, it would incorrectly associate the trust value of the UID with the highest trust value with every other UID assigned to that key. This prevents a warning message from...
