  X.690) encoding and decoding functions. The following packages have been
  upgraded to a later upstream version: libtasn1 (4.10). (BZ#1360639) Security
  Fix(es): * A heap-based buffer overflow flaw was found in the way the libtasn1
  library decoded certain DER-encoded inputs. A specially crafted DER-encoded
  input could cause an application using libtasn1 to perform an invalid read,
  causing the application to crash. (CVE-2015-3622) * A stack-based buffer
  overflow was found in the way libtasn1 decoded certain DER encoded data. An
  attacker could use this flaw to crash an application using the libtasn1 library.
  (CVE-2015-2806) Additional Changes: For detailed information on changes in this
  release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the
