On June 5th, 2014 a vulnerability (CVE-2014-0224) was found in OpenSSL that impacts our network security products. Fortunately, as of the publication of this article, there are no known in-the-wild attacks. Of course, as you’ve come to expect from Sophos, we’ve wasted no time in getting to work on patches to fix this vulnerability.
The vulnerability exists in OpenSSL and can allow an attacker using a man-in-the-middle attack to decrypt and modify traffic between a vulnerable client and server. Both client and server must be vulnerable for this exploit to work. OpenSSL versions 1.0.1 and 1.0.2-beta are affected.
