(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 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 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)

  - A flaw exists in the 'ssl3_client_hello()' function due to improper validation of a PRNG seed before proceeding with a handshake, resulting in insufficient entropy and predictable output.
