CVE-2026-119195 pyasn1: Quadratic-time denial of service in constructed string and indefinite-length ANY decoding

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.5, constructed string and indefinite-length ANY decoding repeatedly concatenates each fragment onto a growing bytes value. Attacker-controlled BER or CER data can use many constructed OCTET STRING or character-string fragments. DER reject...
