Description of the vulnerability
Several vulnerabilities were announced in OpenSSL.
An attacker can send a DTLS message, to force a NULL pointer to be dereferenced in dtls1_get_record(), in order to trigger a denial of service. [severity:2/4; CVE-2014-3571]
An attacker can send a DTLS message, to create a memory leak in dtls1_buffer_record(), in order to trigger a denial of service. [severity:1/4; CVE-2015-0206]
An attacker can force a TLS client to use ECDH instead of ECDHE (ephemeral). [severity:2/4; CVE-2014-3572]
An attacker can force a TLS client to use EXPORT_RSA instead of RSA (VIGILANCE-VUL-16301). [severity:2/4; CVE-2015-0204, VU#243585]
An attacker can authenticate without using a private key, in the case where the server trusts a certification authority publishing certificates with DH keys (rare case) (VIGILANCE-VUL-16300). [severity:2/4; CVE-2015-0205]
An attacker can change the fingerprint of a certificate, with no known consequence on security. [severity:1/4; CVE-2014-8275]
In some rare cases, the BN_sqr() function produces an invalid result, with no known consequence on security. [severity:1/4; CVE-2014-3570]
