Security Update: What you need to know about the Heartbleed Bug
The “Heartbleed” vulnerability, first announced to the public on April 7, 2014, refers to a bug that is present in versions 1.0.1 through 1.0.1f of the OpenSSL security package. OpenSSL is a widely-used solution for implementing the SSL and TLS standards by which secure traffic is encrypted and decrypted. This bug, which resulted from a programming error, enables an attacker to read memory from servers running vulnerable versions of OpenSSL, while leaving no trace in any server-side logs.
Installing security updates is an essential measure server administrators (and the businesses that employ them) must take to minimize the risk of sensitive information, such as passwords, banking details, and other types of private data, being leaked. Using the following testing sites, you can determine if your services are affected by the Heartbleed bug.
