no problems reported so far, so I think we can progress.

CVE-2014-3469 (
  The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU
  Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of
  service (NULL pointer dereference and crash) via a NULL value in an ivalue

CVE-2014-3468 (
  The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly
  report an error when a negative bit length is identified, which allows
  context-dependent attackers to cause out-of-bounds access via crafted ASN.1

CVE-2014-3467 (
  Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1
  before 3.6, as used in GnutTLS, allow remote attackers to cause a denial of
  service (out-of-bounds read) via a crafted ASN.1 data.
