Update CHANGES and NEWS

 Changes between 1.0.1m and 1.0.1n [xx XXX xxxx]

  *) Malformed ECParameters causes infinite loop

     When processing an ECParameters structure OpenSSL enters an infinite loop

     if the curve specified is over a specially malformed binary polynomial

     field.

     This can be used to perform denial of service against any

     system which processes public keys, certificate requests or

     certificates.  This includes TLS clients and TLS servers with

     client authentication enabled.

     This issue was reported to OpenSSL by Joseph Barr-Pixton.

     (CVE-2015-1788)

     [Andy Polyakov]

  *) Exploitable out-of-bounds read in X509_cmp_time

     X509_cmp_time does not properly check the length of the ASN1_TIME

     string and can read a few bytes out of bounds. In addition,

     X509_cmp_time accepts an arbitrary number of fractional seconds in the

     time string.

     An attacker can use this to craft malformed certificates and CRLs of

     various sizes and potentially cause a segmentation fault, resulting in

     a DoS on applications that verify certificates or CRLs. TLS clients

     that verify CRLs are affected. TLS clients and servers with client

     authentication enabled may be affected if they use custom verification

     callbacks.

     This issue was reported to OpenSSL by Robert Swiecki (Google), and

     independently by Hanno Böck.

     (CVE-2015-1789)

     [Emilia Käsper]

  *) PKCS7 crash with missing EnvelopedContent

     The PKCS#7 parsing code does not handle missing inner EncryptedContent

     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 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-2015-1790)

     [Emilia Käsper]

  *) CMS verify infinite loop with unknown hash function

     When verifying a signedData message the CMS code can enter an infinite loop

     if presented with an unknown hash function OID. This can be used to perform

     denial of service against any system which verifies signedData messages using

     the CMS code.

     This issue was reported to OpenSSL by Johannes Bauer.

     (CVE-2015-1792)

     [Stephen Henson]

  *) Race condition handling NewSessionTicket

     If a NewSessionTicket is received by a multi-threaded client when attempting to

     reuse a previous ticket then a race condition can occur potentially leading to

     a double free of the ticket data.

     (CVE-2015-1791)

     [Matt Caswell]

  *) Reject DH handshakes with parameters shorter than 768 bits.

     [Kurt Roeckx and Emilia Kasper]
