| Detailed Description |
According to its banner, the remote web server uses a version of OpenSSL older than 0.9.8zf. Such versions may be affected by the following vulnerabilities :
- A use-after-free condition exists in the d2i_ECPrivateKey() function due to improper processing of malformed EC private key files during import. A remote attacker can exploit this to dereference or free already freed memory, resulting in a denial of service or other unspecified impact. (CVE-2015-0209)
- An invalid read flaw exists in the ASN1_TYPE_cmp() function due to improperly performed boolean-type comparisons. A remote attacker can exploit this, via a crafted X.509 certificate to an endpoint that uses the certificate-verification feature, to cause an invalid read operation, resulting in a denial of service. (CVE-2015-0286)
- A flaw exists in the ASN1_item_ex_d2i() function due to a failure to reinitialize 'CHOICE' and 'ADB' data structures when reusing a structure in ASN.1 parsing. This allows a remote attacker to cause an invalid write operation and memory corruption, resulting in a denial of service. (CVE-2015-0287)
- A NULL pointer dereference flaw exists in the X509_to_X509_REQ() function due to improper processing of certificate keys. This allows a remote attacker, via a crafted X.509 certificate, to cause a denial of service. (CVE-2015-0288)
- A NULL pointer dereference flaw exists in the PKCS#7 parsing code due to incorrect handling of missing outer ContentInfo. This allows a remote attacker, using an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, to cause a denial of service. (CVE-2015-0289)
- A flaw exists in servers that both support SSLv2 and enable export cipher suites due to improper implementation of SSLv2. A remote attacker can exploit this, via a crafted CLIENT-MASTER-KEY message, to cause a denial of service. (CVE-2015-0293)
