Background
OpenSSL is an open-source software library that provides cryptographic functions to secure communications over computer networks. It is widely used in various applications, including web servers, email servers, and virtual private networks (VPNs). This vulnerability affects OpenSSL version 1.0.1t-1+deb7u4 on Debian 7 Wheezy.
Vulnerability Detail
The vulnerability in OpenSSL involves constructed ASN.1 types with a recursive definition that could cause a stack overflow, leading to a denial of service. An attacker could exploit this vulnerability by sending specially crafted ASN.1 data to a vulnerable system, causing it to crash or become unresponsive. This could potentially disrupt the availability of services relying on OpenSSL.
How To Fix
