CVE-2026-34180

Issue summary: Parsing a crafted DER-encoded ASN.1 structure with a primitive element whose content exceeds 2 gigabytes in length may cause a heap buffer over-read on 64-bit Unix and Unix-like platforms. Impact summary: The heap buffer over-read may crash the application Denial of Service or to...

CVE-2026-33894

Forge also called node-forge is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, RSASSA PKCS1 v1.5 signature verification accepts forged signatures for low public exponent keys e=3. Attackers can forge signatures by stuffing “garbage” bytes within the ASN...

CVE-2025-66031 pertains to the node-forge (Forge) library. An Uncontrolled Recursion vulnerability in node-forge

openssl: ASN.1 structure reuse memory corruption

An out-of-bounds write flaw was found in the way OpenSSL reused certain ASN.1 structures. A remote attacker could possibly use a specially crafted ASN.1 structure that, when parsed by an application, would cause that application to crash...

CVE-2015-0287

The ASN1itemexd2i function in crypto/asn1/tasndec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service invalid write operation and memory...

UBUNTU-CVE-2015-0287

The ASN1itemexd2i function in crypto/asn1/tasndec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service invalid write operation and memory...

libtasn1: DER decoding buffer overflow (GNUTLS-SA-2012-3, MU-201202-02)

The asn1getlengthder function in decoding.c in GNU Libtasn1 before 2.12, as used in GnuTLS before 3.0.16 and other products, does not properly handle certain large length values, which allows remote attackers to cause a denial of service heap memory corruption and application crash or possibly ha...

Vulnerability in OpenSSL CVE-2009-0789

When a malformed ASN1 structure is received it’s contents are freed up and zeroed and an error condition returned. On a small number of platforms where sizeoflong sizeofvoid for example WIN64 this can cause an invalid memory access later resulting in a crash when some invalid structures are read,...

OpenSSL -- Multiple problems in crypto(3)

Problem Description: Several problems have been found in OpenSSL: During the parsing of certain invalid ASN1 structures an error condition is mishandled, possibly resulting in an infinite loop. A buffer overflow exists in the SSLgetsharedciphers function. A NULL pointer may be dereferenced in the...
