CVE-2026-30922

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.3, the pyasn1 library is vulnerable to a Denial of Service DoS attack caused by uncontrolled recursion when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing thousands of nested SEQUENC...

GHSA-JR27-M4P2-RC6R Denial of Service in pyasn1 via Unbounded Recursion

Summary The pyasn1 library is vulnerable to a Denial of Service DoS attack caused by uncontrolled recursion 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. This...

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-2026-1260 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...

TencentOS Server 4: python-pyasn1 (TSSA-2026:0038)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0038 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:...

📄 OpenSSL 3.x ASN.1 AES‑GCM Nonce Stack Corruption

This Metasploit auxiliary module generates a specially crafted CMS file encoded in DER format to test a stack-based buffer overflow vulnerability in OpenSSL's ASN.1 parser related to improper handling of oversized AES-GCM nonce IV values within AES-GCM-Parameters as defined in RFC 5084. The...

CVE-2024-34235

Open5GS MME versions = 2.6.4 contains an assertion that can be remotely triggered via a malformed ASN.1 packet over the S1AP interface. An attacker may send an Initial UE Message missing a required NASPDU field to repeatedly crash the MME, resulting in denial of service...

CVE-2019-18840

In wolfSSL 4.1.0 through 4.2.0c, there are missing sanity checks of memory accesses in parsing ASN.1 certificate data while handshaking. Specifically, there is a one-byte heap-based buffer overflow inside the DecodedCert structure in GetName in wolfcrypt/src/asn.c because the domain name location...

CVE-2019-16748

In wolfSSL through 4.1.0, there is a missing sanity check of memory accesses in parsing ASN.1 certificate data while handshaking. Specifically, there is a one-byte heap-based buffer over-read in CheckCertSignatureex in wolfcrypt/src/asn.c...

CVE-2025-12816

A flaw was found in node-forge. This vulnerability allows unauthenticated attackers to bypass downstream cryptographic verifications and security decisions via crafting ASN.1 Abstract Syntax Notation One structures to desynchronize schema validations, yielding a semantic divergence. Mitigation...
