The version of OpenSSL running on the remote host is affected by the following vulnerabilities :
The implementation of Cryptographic Message Syntax (CMS) and PKCS #7 in OpenSSL does not properly restrict certain oracle behavior, which makes it easier for context-dependent attackers to decrypt data via a Million Message Attack (MMA) adaptive chosen ciphertext attack. (CVE-2012-0884)
The mime_param_cmp function in crypto/asn1/asn_mime.c in OpenSSL allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted S/MIME message, a different vulnerability than CVE-2006-7250. (CVE-2012-1165)
The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in OpenSSL does not properly interpret integer data, which allows remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key. (CVE-2012-2110)
Multiple integer signedness errors in crypto/buffer/buffer.c in OpenSSL allow remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-2110. (CVE-2012-2131)
Integer underflow in OpenSSL when TLS 1.1, TLS 1.2, or DTLS is used with CBC encryption, allows remote attackers to cause a denial of service (buffer over- read) or possibly have unspecified other impact via a crafted TLS packet that is not properly handled during a certain explicit IV calculation.
