+    gpg: Import only packets which are allowed in a keyblock.
+    
+    * g10/import.c (valid_keyblock_packet): New.
+    (read_block): Store only valid packets.
+    --
+    
+    A corrupted key, which for example included a mangled public key
+    encrypted packet, used to corrupt the keyring.  This change skips all
+    packets which are not allowed in a keyblock.
