Recent Attacks against OpenSSL likely to be applicable to other SSL implementations

In the past two months, there has been significant new research into the security of OpenSSL, the open source implementation of the Secure Sockets Layer (SSL). OpenSSL is the standard SSL implementation included with most Linux distributions, and as such is the most common choice for running secure websites with Apache. At least one quarter of public SSL sites use OpenSSL according to our most recent SSL Server Survey.
