CVE-2015-0209
It was discovered that a malformed EC private key might result in memory corruption.
CVE-2015-0286
Stephen Henson discovered that the ASN1_TYPE_cmp() function can be crashed, resulting in denial of service.
CVE-2015-0287
Emilia Kaesper discovered a memory corruption in ASN.1 parsing.
CVE-2015-0288
It was discovered that missing input sanitising in the X509_to_X509_REQ() function might result in denial of service.
CVE-2015-0289
Michal Zalewski discovered a NULL pointer dereference in the PKCS#7 parsing code, resulting in denial of service.
CVE-2015-0292
It was discovered that missing input sanitising in base64 decoding might result in memory corruption.
CVE-2015-0293
A malicious client can trigger an OPENSSL_assert (i.e., an abort) in servers that both support SSLv2 and enable export cipher suites by sending a specially crafted SSLv2 CLIENT-MASTER-KEY message.
