CVE-2026-33936

CVE-2026-33936 affects the Python package python-ecdsa (pre-0.19.2). A flaw in the low-level DER parsing (remove_octet_string) can cause generated truncated DER inputs to be accepted, allowing SigningKey.from_der() to raise an internal IndexError instead of rejecting malformed data, potentially c...

CVE-2026-33936

The ecdsa PyPI package is a pure Python implementation of ECC Elliptic Curve Cryptography with support for ECDSA Elliptic Curve Digital Signature Algorithm, EdDSA Edwards-curve Digital Signature Algorithm and ECDH Elliptic Curve Diffie-Hellman. Prior to version 0.19.2, an issue in the low-level D...

📄 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...

Uncontrolled Recursion

Overview org.webjars.npm:node-forge is a WebJar for node-forge. Affected versions of this package are vulnerable to Uncontrolled Recursion via the fromDer function in asn1.js, which lacks recursion depth. An attacker can cause stack exhaustion and disrupt service availability by submitting...

CVE-2025-32029

ts-asn1-der is a collection of utility classes to encode ASN.1 data following DER rule. Incorrect number DER encoding can lead to denial on service for absolute values in the range 231 -- 232 - 1. The arithmetic in the numBitLen didn't take into account that values in this range could result in a...

GHSA-P4QW-7J9G-5H53 ts-asn1-der has Incorrect DER Encoding of Numbers Leading to Denial of Service and Incorrect Value Representation

Impact Incorrect number DER encoding can lead to denial on service for absolute values in the range 231 -- 232 - 1. The arithmetic in the numBitLen didn't take into account that values in this range could result in a negative result upon applying the operator, leading to an infinite loop. In...
