Synopsis :

The remote server is affected by multiple vulnerabilities.

Description :

According to its banner, the remote server is running a version of
OpenSSL that is earlier than 0.9.7l or 0.9.8d. As such, it is
affected by multiple vulnerabilities :

- A remote attacker could trigger a denial of service,
either via malformed ASN.1 structures or specially
crafted public keys. (CVE-2006-2937, CVE-2006-3738)

- A remote attacker could execute arbitrary code on the
remote server by exploiting a buffer overflow in the
SSL_get_shared_ciphers function. (CVE-2006-2940)

- A remote attacker could crash a client by sending an
invalid server Hello. (CVE-2006-4343)
