Recently a serious vulnerability was found in OpenSSL cryptographic software library. The Fix was released on 7th April, 2014, the OpenSSL version which fixes the bug is 1.0.1g.
Currently the servers running Virtualizor VPS Panel are vulnerable to Heartbleed bug, because we maintain our own EMPS package. We have updated our Virtualizor EMPS Stack which overcomes this vulnerability and we highly recommend to update your Virtualizor EMPS Stack. We are also releasing the new Virtualizor Version which will automatically fix the issue.
Until the new Virtualizor version is launched, you can manually update the Virtualizor EMPS using the following command :
root> /usr/local/emps/bin/php /usr/local/virtualizor/scripts/emps.php update
If you need any assistance updating the EMPS, please contact the Virtualizor support team.
What is the Heartbleed Bug ?
The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).
The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.
