Details

It was discovered that tgt incorrectly handled long iSCSI name strings, and
invalid PDUs. A remote attacker could exploit this to cause tgt to crash,
resulting in a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 10.10. (CVE-2010-2221)

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.
