  script_tag(name:"insight", value:"libressl was updated to version 2.2.1 to fix 16 security issues.

  LibreSSL is a fork of OpenSSL. Because of that CVEs affecting OpenSSL
  often also affect LibreSSL.

  These security issues were fixed:

  - CVE-2014-3570: The BN_sqr implementation in OpenSSL before 0.9.8zd,
  1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k did not properly calculate
  the square of a BIGNUM value, which might make it easier for remote
  attackers to defeat cryptographic protection mechanisms via unspecified
  vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c,
  and crypto/bn/bn_asm.c (bsc#912296).

  - CVE-2014-3572: The ssl3_get_key_exchange function in s3_clnt.c in
  OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k
  allowed remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks
  and trigger a loss of forward secrecy by omitting the ServerKeyExchange
  message (bsc#912015).

  - CVE-2015-1792: The do_free_upto function in crypto/cms/cms_smime.c in
  OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and
  1.0.2 before 1.0.2b allowed remote attackers to cause a denial of
  service (infinite loop) via vectors that trigger a NULL value of a BIO
  data structure, as demonstrated by an unrecognized X.660 OID for a hash
  function (bsc#934493).

  - CVE-2014-8275: OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1
  before 1.0.1k did not enforce certain constraints on certificate data,
  which allowed remote attackers to defeat a fingerprint-based
  certificate-blacklist protection mechanism by including crafted data
  within a certificate's unsigned portion, related to
  crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c,
  and crypto/x509/x_all.c (bsc#912018).

  - CVE-2015-0209: Use-after-free vulnerability in the d2i_ECPrivateKey
  function in crypto/ec/ec_asn1.c in OpenSSL before 0.9.8zf, 1.0.0 before
  1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allowed
  remote attackers to cause a denial of service (memory corruption and
  application crash) or possibly have unspecified other impact via a
  malformed Elliptic Curve (EC) private-key file that is improperly
  handled during import (bsc#919648).

  - CVE-2015-1789: The X509_cmp_time function in crypto/x509/x509_vfy.c in
  OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and
  1.0.2 before 1.0.2b allowed remote attackers to cause a denial of
  service (out-of-bounds read and application crash) via a crafted length
  field in ASN1_TIME data, as demonstrated by an attack against a server
  that supports client authentication with a custom verific ...
