CVE-2026-59886 pyasn1: Uncontrolled resource consumption when converting decoded REAL values

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the univ.Real type converted its mantissa, base, and exponent value to a Python float using exact big-integer exponentiation. A BER, CER, or DER encoded REAL value only a few bytes long can carry a very large exponent, causing float...

CVE-2026-59886

Summary: pyasn1 before 0.6.4 contains a vulnerability in the univ.Real ASN.1 type where mantissa/base/exponent are converted to a Python float via exact big-integer exponentiation. This can cause excessive CPU/memory usage when decoding untrusted ASN.1 data and subsequently printing, logging, or ...
