pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...

EUVD-2026-21290

An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name SAN extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect...

USN-8129-1: pyasn1 vulnerability

It was discovered that pyasn1 incorrectly handled recursion when decoding ASN.1 data. An attacker could use this issue to cause pyasn1 to consume resources, leading to a denial of service...

OESA-2026-1776 python-pyasn1 security update

Abstract Syntax Notation One ASN.1 is a technology for exchanging structured data in a universally understood, hardware agnostic way. Many industrial, security and telephony applications heavily rely on ASN.1. The pyasn1 library implements ASN.1 support in pure-Python. Security Fixes: The pyasn1...
