+ Changes between 1.0.1l and 1.0.1m [19 Mar 2015]
+
+  *) Segmentation fault in ASN1_TYPE_cmp fix
+
+     The function ASN1_TYPE_cmp will crash with an invalid read if an attempt is
+     made to compare ASN.1 boolean types. Since ASN1_TYPE_cmp is used to check
+     certificate signature algorithm consistency this can be used to crash any
+     certificate verification operation and exploited in a DoS attack. Any
+     application which performs certificate verification is vulnerable including
+     OpenSSL clients and servers which enable client authentication.
+     (CVE-2015-0286)
+     [Stephen Henson]
+
+  *) ASN.1 structure reuse memory corruption fix
+
+     Reusing a structure in ASN.1 parsing may allow an attacker to cause
+     memory corruption via an invalid write. Such reuse is and has been
+     strongly discouraged and is believed to be rare.
+
+     Applications that parse structures containing CHOICE or ANY DEFINED BY
+     components may be affected. Certificate parsing (d2i_X509 and related
+     functions) are however not affected. OpenSSL clients and servers are
+     not affected.
+     (CVE-2015-0287)
+     [Stephen Henson]
+
+  *) PKCS7 NULL pointer dereferences fix
+
+     The PKCS#7 parsing code does not handle missing outer ContentInfo
+     correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs with
+     missing content and trigger a NULL pointer dereference on parsing.
+
+     Applications that verify PKCS#7 signatures, decrypt PKCS#7 data or
+     otherwise parse PKCS#7 structures from untrusted sources are
+     affected. OpenSSL clients and servers are not affected.
+
+     This issue was reported to OpenSSL by Michal Zalewski (Google).
+     (CVE-2015-0289)
+     [Emilia Käsper]
+
+  *) DoS via reachable assert in SSLv2 servers fix
+
+     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.
+
+     This issue was discovered by Sean Burford (Google) and Emilia Käsper
+     (OpenSSL development team).
+     (CVE-2015-0293)
+     [Emilia Käsper]
+
+  *) Use After Free following d2i_ECPrivatekey error fix
+
+     A malformed EC private key file consumed via the d2i_ECPrivateKey function
+     could cause a use after free condition. This, in turn, could cause a double
+     free in several private key parsing functions (such as d2i_PrivateKey
+     or EVP_PKCS82PKEY) and could lead to a DoS attack or memory corruption
+     for applications that receive EC private keys from untrusted
+     sources. This scenario is considered rare.
+
+     This issue was discovered by the BoringSSL project and fixed in their
+     commit 517073cd4b.
+     (CVE-2015-0209)
+     [Matt Caswell]
+
+  *) X509_to_X509_REQ NULL pointer deref fix
+
+     The function X509_to_X509_REQ will crash with a NULL pointer dereference if
+     the certificate key is invalid. This function is rarely used in practice.
+
+     This issue was discovered by Brian Carpenter.
+     (CVE-2015-0288)
+     [Stephen Henson]
 
   *) Removed the export ciphers from the DEFAULT ciphers
      [Kurt Roeckx]
