Log message:
Updated libtasn1 to 4.8. Security update.

* Noteworthy changes in release 4.8 (released 2016-04-11) [stable]
- Fixes to avoid reliance on C undefined behavior.
- Fixes to avoid an infinite recursion when decoding without
  the ASN1_DECODE_FLAG_STRICT_DER flag. Reported by Pascal Cuoq.
- Combined all the BER octet string decoding functions to a single
  one based on asn1_decode_simple_ber().

* Noteworthy changes in release 4.7 (released 2015-09-14) [stable]
- Fixed regression introduced in the decoding of multi-byte tags
  fix.

* Noteworthy changes in release 4.6 (released 2015-09-05) [stable]
- Allow decoding OCTET STRINGs with multi-byte tags.
- API and ABI changes since last version:
  asn1_get_object_id_der: New function

Log message:
Use OPSYSVARS.

Log message:
Add SHA512 digests for distfiles for security category

Problems found locating distfiles:
	Package f-prot-antivirus6-fs-bin: missing distfile fp-NetBSD.x86.32-fs-6.2.3.tar.gz
	Package f-prot-antivirus6-ws-bin: missing distfile fp-NetBSD.x86.32-ws-6.2.3.tar.gz

	Package uvscan: missing distfile vlp4510e.tar.Z

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Update to 4.5:

* Noteworthy changes in release 4.5 (released 2015-04-29) [stable]
- Corrected an invalid memory access in octet string decoding.
  Reported by Hanno Böck.

Log message:
Update to 4.4, security release.

* Noteworthy changes in release 4.4 (released 2015-03-29) [stable]
- Corrected a two-byte stack overflow in asn1_der_decoding. Reported
  by Hanno Böck.

* Noteworthy changes in release 4.3 (released 2015-03-09) [stable]
- Added asn1_decode_simple_ber()

Log message:
Changes 4.2:
- Added sanity checks in the decoding of time when
  ASN1_DECODE_FLAG_STRICT_DER is used.
- Fixes in the decoding of OCTET STRING when close to the end
  of the structure.

Log message:
Remove pkgviews: don't set PKG_INSTALLATION_TYPES in Makefiles.

Log message:
Changes 3.6:
- Corrected an off-by-one error in ASN.1 DER tag decoding.
- Several improvements and new safety checks on DER decoding;
  issues found using Codenomicon TLS test suite.
- Marked asn1_der_decoding_element() as deprecated. Use
  asn1_der_decoding() instead.

Log message:
Changes 3.5:
- Correctly handle decoding of recursive CHOICE options.
- Allow deleting elements of SET OF.
- Several small bug fixes found by coverity.
- Code improvements

Log message:
Update to 3.1:

* Noteworthy changes in release 3.1 (released 2012-11-24) [stable]
- Completed rename of types:
  ASN1_ARRAY_TYPE -> asn1_static_node (was asn1_static_node_t)
- Added new types: VisibleString, NumericString, IA5String, TeletexString,
  PrintableString, UniversalString, BMPString, UTF8String. When re-defined
  a warning is being print instead of failing.
- Parser outputs more detailed syntax error messages.
- Added asn1_decode_simple_der() and asn1_encode_simple_der().
- Added asn1_read_value_type() to return value and type.
- Introduced ASN1_ETYPE_UTC_TIME and ASN1_ETYPE_GENERALIZED_TIME

* Noteworthy changes in release 3.0 (2012-10-28) [stable]
- Added tool in tests/ to benchmark X.509 structure decoding.
- Added asn1_read_node_value() to obtain a node's value.
- Optimizations in internal tree allocation.
- Optimizations in tree search.
- libtasn1.h no longer exports internal structures.
- Types were renamed for consistency:
  ASN1_DATA_NODE -> asn1_data_node_st
  ASN1_ARRAY_TYPE -> asn1_static_node
  ASN1_TYPE -> asn1_node
  ASN1_TYPE_EMPTY -> NULL
  static_struct_asn -> asn1_static_node_st
  node_asn_struct -> asn1_node_st
  node_asn -> asn1_node_st
  (the old types are still available as definitions)
