tag_insight = "The GnuTLS Library provides support for cryptographic algorithms and
  protocols such as TLS. GnuTLS includes libtasn1, a library developed for
  ASN.1 structures management that includes DER encoding and decoding.

  Flaws were found in the way GnuTLS handles malicious client connections. A
  malicious remote client could send a specially crafted request to a service
  using GnuTLS that could cause the service to crash. (CVE-2008-1948,
  CVE-2008-1949, CVE-2008-1950)
  
  We believe it is possible to leverage the flaw CVE-2008-1948 to execute
  arbitrary code but have been unable to prove this at the time of releasing
  this advisory. Red Hat Enterprise Linux 4 does not ship with any
  applications directly affected by this flaw. Third-party software which
  runs on Red Hat Enterprise Linux 4 could, however, be affected by this
  vulnerability. Consequently, we have assigned it important severity.
  
  Users of GnuTLS are advised to upgrade to these updated packages, which
  contain a backported patch that corrects these issues.";
