pyasn1: pyasn1: Denial of Service due to memory exhaustion from malformed RELATIVE-OID

A flaw was found in pyasn1, a generic ASN.1 library for Python. A remote attacker could exploit this vulnerability by sending a specially crafted RELATIVE-OID with excessive continuation octets. This input validation vulnerability leads to memory exhaustion, resulting in a Denial of Service DoS f...

OESA-2026-1261 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: pyasn1 is a...

USN-7975-1 pyasn1 vulnerability

It was discovered that pyasn1 incorrectly handled malformed RELATIVE-OIDs with excessive continuation octets. An attacker could possibly use this issue to cause pyasn1 to consume memory, leading to a denial of service...

CVE-2026-23490

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.2, a Denial-of-Service issue has been found that leads to memory exhaustion from malformed RELATIVE-OID with excessive continuation octets. This vulnerability is fixed in 0.6.2...
