tag_insight = "libtasn1 is a library developed for ASN.1 (Abstract Syntax Notation One)
  structures management that includes DER (Distinguished Encoding Rules)
  encoding and decoding.

  A flaw was found in the way libtasn1 decoded DER data. An attacker could
  create carefully-crafted DER encoded input (such as an X.509 certificate)
  that, when parsed by an application that uses libtasn1 (such as
  applications using GnuTLS), could cause the application to crash.
  (CVE-2012-1569)
  
  Red Hat would like to thank Matthew Hall of Mu Dynamics for reporting this
  issue.
  
  Users of libtasn1 are advised to upgrade to these updated packages, which
  contain a backported patch to correct this issue. For the update to take
  effect, all applications linked to the libtasn1 library must be restarted,
  or the system rebooted.";
