Background
OpenSSL is an open-source software library that provides cryptographic functions for secure communication over computer networks. It is widely used in various applications, including web servers, email servers, and virtual private networks (VPNs). This vulnerability affects the OpenSSL package in the Debian 7 ecosystem.
Vulnerability Detail
A programming error in the TLS handshake package of OpenSSL allows an attacker to crash the software by sending an invalid handshake package. This can lead to a NULL pointer dereference, causing the software to terminate unexpectedly. The vulnerability can be exploited remotely, potentially leading to denial-of-service (DoS) attacks against systems using the affected version of OpenSSL.
