"The version of OpenSSL installed on the remote host is prior to 1.0.1n. It is, therefore, affected by multiple
vulnerabilities as referenced in the 1.0.1n advisory.
- The do_free_upto function in crypto/cms/cms_smime.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1
before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (infinite
loop) via vectors that trigger a NULL value of a BIO data structure, as demonstrated by an unrecognized
X.660 OID for a hash function. (CVE-2015-1792)
- The PKCS7_dataDecodefunction in crypto/pkcs7/pk7_doit.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s,
1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (NULL
pointer dereference and application crash) via a PKCS#7 blob that uses ASN.1 encoding and lacks inner
EncryptedContent data. (CVE-2015-1790)
- The X509_cmp_time function in crypto/x509/x509_vfy.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1
before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (out-of-bounds
read and application crash) via a crafted length field in ASN1_TIME data, as demonstrated by an attack
against a server that supports client authentication with a custom verification callback. (CVE-2015-1789)
- The BN_GF2m_mod_inv function in crypto/bn/bn_gf2m.c in OpenSSL before 0.9.8s, 1.0.0 before 1.0.0e, 1.0.1
before 1.0.1n, and 1.0.2 before 1.0.2b does not properly handle ECParameters structures in which the curve
is over a malformed binary polynomial field, which allows remote attackers to cause a denial of service
(infinite loop) via a session that uses an Elliptic Curve algorithm, as demonstrated by an attack against
a server that supports client authentication. (CVE-2015-1788)
- Race condition in the ssl3_get_new_session_ticket function in ssl/s3_clnt.c in OpenSSL before 0.9.8zg,
1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b, when used for a multi-threaded client,
allows remote attackers to cause a denial of service (double free and application crash) or possibly have
unspecified other impact by providing a NewSessionTicket during an attempt to reuse a ticket that had been
obtained earlier. (CVE-2015-1791)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
