Bumps pyasn1 from 0.6.4 to 0.6.5.

Release notes

Sourced from pyasn1's releases.

Release 0.6.5

Revision 0.6.5, released 26-10-2026

  • GHSA-mm57-4v3p-rchx: Decoded binary REAL mantissas in linear time instead of repeatedly shifting a growing integer and slicing the remaining bytes (thanks for reporting, manus-use, manus-pi, ucsurf, adriank31)
  • GHSA-2qm8-x737-gmw5: Reassembled constructed BIT STRING fragments in linear time while preserving their decoded bit values, including intermediate fragment padding (thanks for reporting, manus-use)
  • GHSA-9m75-vc3g-4x39: Reassembled constructed OCTET STRING and character-string fragments and indefinite-length ANY content in linear time. Nested constructed OCTET STRING fragments now contribute their decoded octets (thanks for reporting, alimony, manus-pi, adriank31)
  • GHSA-fm9c-5rcf-2q5p: Bounded schemaless container type tracking after two distinct tag sets to prevent quadratic CPU use from colliding long tag IDs (thanks for reporting, droideck)

Summary by cubic

Updates pyasn1 from 0.6.4 to 0.6.5 to fix DoS vulnerabilities that caused quadratic CPU use when decoding binary REAL mantissas, constructed BIT STRING and OCTET STRING fragments, and schemaless containers. The lock file also includes unrelated changes from uv normalizing platform markers and adding the pyobjc-framework-pubsub package.
