Bump pyasn1 from 0.6.3 to 0.6.4

[dependabot]

Bumps pyasn1 from 0.6.3 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.

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)

PR #728 bumps pyasn1 0.6.3 → 0.6.4 in uv.lock — a patch-level security release.

• Semver risk: patch
• Dependency type: transitive, optional production extra (google_drive → google-auth → pyasn1-modules → pyasn1); not in base dependencies
• Security fixes: three DoS-class CVEs — CVE-2026-59885 (quadratic-time OID/RELATIVE-OID decoding; decoded values unchanged), CVE-2026-59884 (BER long-form tag IDs now capped at 20 octets, longer ones raise PyAsn1Error), CVE-2026-59886 (Real.__float__() raises OverflowError promptly instead of grinding; base-10 mantissa normalization now exact)
• Breaking changes: none declared. Two intentional hardening changes: pathological >20-octet tag IDs are rejected, and Real → float results above 2**53 mantissa are now exact rather than lossy.
• Peer/transitive changes: none — pyasn1 remains dependency-free, pyasn1-modules stays at 0.4.2 with an unpinned pyasn1 requirement
• Code changes required: none — no pyasn1 usage in ricecooker source; all use is inside google-auth parsing trusted service-account key material
• CI: passing (11/11 runs on 22ad28a)

Lockfile diff is 3 lines confined to the pyasn1 block — version, sdist hash, wheel hash. No transitive churn smuggled in.

@rtibblesbot's comments are generated by an LLM, and should be evaluated accordingly

How was this generated?

Ran a dependency-update review pipeline over the version bump:

• Classified the bump by semver (patch / minor / major) and dependency type (production vs. development)
• Extracted the changelog and release notes across the version range
• Assessed compatibility with this project's usage and whether any code changes are required
• Treated CI as the primary safety net
• Scaled the review depth to the update's risk
• Chose the verdict from semver risk, changelog findings, and CI status
