The Heartbleed OpenSSL bug is unlike virtually any Internet-based security threat you’ve probably ever heard of. It’s not a virus that’s specific to one operating system or type of device. Since it revolves around a flaw in the method of encryption used by many of the world’s websites, this problem potentially affects almost everyone who uses the Internet, including people who operate servers that run Ubuntu Linux, the free, open-source operating system.
