OpenSSL Issues Fix

Filed under
Software
Security

The OpenSSL server has been patched to repair a critical security glitch that could be exploited in remote code execution attacks.

OpenSSL is a toolkit that implements Secure Sockets Layer and Transport Layer Security protocols, as well as a full strength, general purpose cryptography library.

The race condition flaw was found in the OpenSSL TLS server extension parsing code, affecting some multithreaded OpenSSL applications. Researchers at Red Hat Security, which relies on OpenSSL for an array of Red Hat Enterprise Linux products, warned in an advisory that under certain conditions, attackers could exploit the vulnerability by triggering a race condition that could cause the OpenSSL application to crash, or enable them to launch of a malicious attack.

The vulnerability, which Red Hat Security researchers ranked as "important" on their Common Vulnerability Scoring System, affects all versions of the OpenSSL supporting TLS extensions, including OpenSSL 0.9.8f through 0.9.8o, 1.0.0 and 1.0.0a.

The Internet Without Connection, Free Endless OS For Emerging Markets

There are four billion people on the planet without PCs or access to affordable personal computers. That figure should surely be tempered with some contextualization i.e. not everybody actually wants to have an Internet connection and many traditional, native or bucolic ways of live do still exist on the planet. Regardless, there are a batch of global initiatives in existence which seek to give computer access to every man, woman and especially child. Endless OS is one such project. The free operating system has been designed explicitly to work in the expensive or restrictive Internet data conditions that often exist in emerging markets where fabulously affordable broadband has yet to arrive. The software itself is built to provide useful information and educational content, with or without an Internet connection. Read more
