Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 4 public exploits for CVE-2014-3570. PoCs published by uthrasri.

AI-analyzed exploit summary This repository contains assembly implementations for Montgomery multiplication and other cryptographic operations, targeting CVE-2014-3570 (a vulnerability in OpenSSL). The code includes hand-optimized assembly for various architectures (Alpha, ARM, x86, etc.) to improve performance in cryptographic operations.

Description

The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c.
