Summary

The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-09:02.openssl.asc

Insight

Insight

FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. The EVP_VerifyFinal() function from OpenSSL is used to determine if a digital signature is valid. The SSL layer in OpenSSL uses EVP_VerifyFinal(), which in several places checks the return value incorrectly and treats verification errors as a good signature. This is only a problem for DSA and ECDSA keys.

Solution

Solution

Upgrade your system to the appropriate stable release or security branch dated after the correction date https://secure1.securityspace.com/smysecure/catid.html?in=FreeBSD-SA-09:02.openssl.asc
