The remote host is missing an update for the Debian 'openssl' package(s) announced via the DSA-2162-1 advisory. Neel Mehta discovered that an incorrectly formatted ClientHello handshake message could cause OpenSSL to parse past the end of the message. This allows an attacker to crash an application using OpenSSL by triggering an invalid memory access. Additionally, some applications may be vulnerable to expose contents of a parsed OCSP nonce extension. We recommend that you upgrade your openssl packages
