Bumps pyasn1 from 0.4.8 to 0.6.4.

Release notes

Sourced from pyasn1's releases.

Release 0.6.4

This is a security release.

  • CVE-2026-59885 (GHSA-8ppf-4f7h-5ppj): Fixed quadratic time complexity in the OBJECT IDENTIFIER and RELATIVE-OID decoders. A small crafted substrate encoding many arcs could consume excessive CPU.
  • CVE-2026-59884 (GHSA-m4p7-r5rc-7g4j): Limited BER long-form tag IDs to 20 octets (140 bits). Unbounded tag IDs allowed a crafted substrate to consume excessive CPU and memory.
  • CVE-2026-59886 (GHSA-hm4w-wwcw-mr6r): Fixed excessive memory and CPU consumption in Real.__float__() for values with large base-10 exponents.
  • Pinned PyPI publish GitHub Action to an immutable commit.

All changes are noted in the CHANGELOG.

Release 0.6.3

It's a minor release.

  • Added nesting depth limit to ASN.1 decoder to prevent stack overflow from deeply nested structures (CVE-2026-30922).
  • Fixed OverflowError from oversized BER length field.
  • Fixed DeprecationWarning stacklevel for deprecated attributes.
  • Fixed asDateTime incorrect fractional seconds parsing.

All changes are noted in the CHANGELOG.

Release 0.6.2

It's a minor release.

  • Fixed continuation octet limits in OID/RELATIVE-OID decoder (CVE-2026-23490).
  • Added support for Python 3.14.
  • Added SECURITY.md policy.
  • Migrated to pyproject.toml packaging.

All changes are noted in the CHANGELOG.

Release 0.6.1

It's a minor release.

  • Added support for Python 3.13.
  • Cleaned Python 2-related code.
  • Removed bdist_wheel universal flag from setup.cfg.

All changes are noted in the CHANGELOG.

Release 0.6.0

It's a major release where we drop Python 2 support entirely. The most significant changes are:

  • Removed support for EOL Python 2.7, 3.6, 3.7
  • Added support for previously missing RELATIVE-OID construct
  • Updated link to Layman's Guide

All changes are noted in the CHANGELOG.

Release 0.5.1

Revision 0.6.4, released 08-07-2026

  • CVE-2026-59885 (GHSA-8ppf-4f7h-5ppj): Fixed quadratic time complexity in the OBJECT IDENTIFIER and RELATIVE-OID decoders. A small crafted substrate encoding many arcs could consume excessive CPU. Arcs are now accumulated in linear time; decoded values are unchanged (thanks for reporting, tynus2)
  • CVE-2026-59884 (GHSA-m4p7-r5rc-7g4j): Limited BER long-form tag IDs to 20 octets (140 bits), matching the OID arc limit introduced in 0.6.2. Unbounded tag IDs allowed a crafted substrate to consume excessive CPU and memory; longer tag IDs are now rejected with PyAsn1Error. Also fixed Tag and TagSet repr() failing on huge tag (thanks for reporting, mikeappsec) IDs due to the integer-to-string conversion limit (Python 3.11+)
  • CVE-2026-59886 (GHSA-hm4w-wwcw-mr6r): Fixed excessive memory and CPU consumption in Real.float() for values with large base-10 exponents. Conversion no longer materializes huge intermediate integers; values too large to represent as a Python float raise OverflowError promptly, and prettyPrint() renders them as '' as before. Also fixed base-10 mantissa normalization to use exact integer arithmetic; mantissas larger than 2**53 could previously lose precision through float division (thanks for reporting, gvozdila)
  • Pinned PyPI publish GitHub Action to an immutable commit [pr #113](pyasn1/pyasn1#113)

Revision 0.6.3, released 16-03-2026
