Log Message:
Update "openssl" package to version 1.0.2b. Changes since version 1.0.2a:
- 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 B�ck.
  (CVE-2015-1789)
  [Emilia K�sper]
- 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 K�sper]
- 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]
- Removed support for the two export grade static DH ciphersuites
  EXP-DH-RSA-DES-CBC-SHA and EXP-DH-DSS-DES-CBC-SHA. These two ciphersuites
  were newly added (along with a number of other static DH ciphersuites) to
  1.0.2. However the two export ones have *never* worked since they were
  introduced. It seems strange in any case to be adding new export
  ciphersuites, and given "logjam" it also does not seem correct to fix them.
  [Matt Caswell]
- Only support 256-bit or stronger elliptic curves with the
  'ecdh_auto' setting (server) or by default (client). Of supported
  curves, prefer P-256 (both).
  [Emilia Kasper]
- Reject DH handshakes with parameters shorter than 768 bits.
  [Kurt Roeckx and Emilia Kasper]
