algorithm of X.509 certificates. If an application linked against
GnuTLS processed a crafted certificate, an attacker could make GnuTLS
dereference a NULL pointer and cause a DoS via application crash.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
