Bump pyasn1 from 0.5.0 to 0.6.4 in /templates/rag-aws-bedrock

[dependabot]

Bumps pyasn1 from 0.5.0 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

• 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)

Note

Low Risk
Lockfile-only transitive dependency security update; no app logic changes. pyasn1 0.6.x requires Python ≥3.8, which matches the template constraint.

Overview
Updates templates/rag-aws-bedrock/poetry.lock so transitive pyasn1 moves from 0.5.0 to 0.6.4 (pulled in via rsa for the AWS CLI/SDK stack). No application source or pyproject.toml changes.

The lockfile was regenerated with Poetry 2.4.1, which also bumps the lock format to 2.1, adds groups on packages, and refreshes assorted metadata and wheel entries—these are tooling/format deltas, not new direct dependencies.

Why: 0.6.4 addresses several ASN.1 decoder/resource exhaustion CVEs (OID/tag parsing, nesting depth, oversized BER lengths, etc.) that affect parsing of untrusted ASN.1 data.
