The not-quite-as-redacted-as-we-intended bit of the TSA leak was a list of countries where the holders of such passports might be asked a few extra questions at check-in.
In case you (and the leaders of international terrorist groups) couldn't have guessed, the countries are:
Cuba, Iran, North Korea, Libya, Syria, Sudan, Afghanistan, Lebanon, Somalia, Iraq, Yemen, or Algeria
Nice to see plucky little Cuba keeping top spot as the USA's most feared enemy.
Sad that Saudi Arabia didn't make the top ten, in spite of the 9/11 hijackers carrying Saudi passports - better luck next time guys ;-)
