pyasn1 (0.6.4-1ubuntu0.1) stonking-security; urgency=medium

  * SECURITY UPDATE: DoS via quadratic binary REAL decoding
    - debian/patches/CVE-2026-119197.patch: decode the REAL mantissa in a single
      conversion in pyasn1/codec/ber/decoder.py,
      tests/codec/ber/test_decoder.py, tests/codec/cer/test_decoder.py,
      tests/codec/der/test_decoder.py.
    - CVE-2026-119197
  * SECURITY UPDATE: DoS via quadratic constructed BIT STRING decoding
    - debian/patches/CVE-2026-119196.patch: assemble constructed BIT STRING
      fragments in linear time in pyasn1/codec/ber/decoder.py,
      tests/codec/ber/test_decoder.py, tests/codec/cer/test_decoder.py,
      tests/codec/der/test_decoder.py.
    - CVE-2026-119196
  * SECURITY UPDATE: DoS via quadratic constructed string and ANY decoding
    - debian/patches/CVE-2026-119195.patch: join constructed string and ANY
      fragments only once in pyasn1/codec/ber/decoder.py,
      tests/codec/ber/test_decoder.py, tests/codec/cer/test_decoder.py,
      tests/codec/der/test_decoder.py.
    - CVE-2026-119195
  * SECURITY UPDATE: DoS via quadratic schemaless container decoding
    - debian/patches/CVE-2026-119194.patch: stop collecting tag sets once two
      distinct types are seen in pyasn1/codec/ber/decoder.py,
      tests/codec/__main__.py, tests/codec/test_decoder_schemaless.py.
