Bump pyasn1 from 0.6.1 to 0.6.4

[dependabot]

Bumps pyasn1 from 0.6.1 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.

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

• CVE-2026-30922 (GHSA-jr27-m4p2-rc6r): Added nesting depth limit to ASN.1 decoder to prevent stack overflow from deeply nested structures (thanks for reporting, romanticpragmatism)
• Fixed OverflowError from oversized BER length field [issue #54](pyasn1/pyasn1#54) [pr #100](pyasn1/pyasn1#100)
• Fixed DeprecationWarning stacklevel for deprecated attributes [issue #86](pyasn1/pyasn1#86) [pr #101](pyasn1/pyasn1#101)
• Fixed asDateTime incorrect fractional seconds parsing [issue #81](pyasn1/pyasn1#81) [pr #102](pyasn1/pyasn1#102)

Revision 0.6.2, released 16-01-2026

• CVE-2026-23490 (GHSA-63vm-454h-vhhq): Fixed continuation octet limits in OID/RELATIVE-OID decoder (thanks to tsigouris007)
• Added support for Python 3.14 [pr #97](pyasn1/pyasn1#97)
