v83.0.0

Features

• Require Python 3.10 or later.

Bugfixes

• MANIFEST.in matching (via FileList) is now insensitive to Unicode normalization form. A pattern authored in one form (e.g. NFC, as typically saved by editors) now matches a file whose name is stored on disk in another (e.g. NFD, as produced by macOS APFS/HFS+). Previously an exclude, global-exclude, recursive-exclude, or prune rule could silently fail to drop a non-ASCII-named file from the source distribution, publishing it despite the exclusion -- see GHSA-h35f-9h28-mq5c.

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.

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)
