AI-analyzed exploit summary This repository contains a proof-of-concept exploit for CVE-2015-1788, a vulnerability in OpenSSL 1.0.1g. The exploit appears to target macOS systems, leveraging socket and string manipulation utilities to demonstrate the vulnerability.

Description

The BN_GF2m_mod_inv function in crypto/bn/bn_gf2m.c in OpenSSL before 0.9.8s, 1.0.0 before 1.0.0e, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b does not properly handle ECParameters structures in which the curve is over a malformed binary polynomial field, which allows remote attackers to cause a denial of service (infinite loop) via a session that uses an Elliptic Curve algorithm, as demonstrated by an attack against a server that supports client authentication.
