"It was discovered that tgt incorrectly handled long iSCSI name

cause tgt to crash, resulting in a denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 10.10.

Emmanuel Bouillon discovered that tgt incorrectly handled certain
iSCSI logins. A remote attacker could exploit this to cause tgt to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2011-0001).

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."
