Actually libtasn1.so.6 has files only distributable under GPL-3+:
lib/ASN.c is licensed under two alternatives:
Either GPL-3+.
Or under terms with restrictions that don't seem compatible with the
GPL or LGPL ("under terms of your choice, so long as that work isn't
itself a parser generator using the skeleton or a modified version
thereof as a parser skeleton").
