CVE-2010-2221

Status Candidate

Overview

Multiple buffer overflows in the iSNS implementation in isns.c in (1) Linux SCSI target framework (aka tgt or scsi-target-utils) before 1.0.6, (2) iSCSI Enterprise Target (aka iscsitarget or IET) 1.4.20.1 and earlier, and (3) Generic SCSI Target Subsystem for Linux (aka SCST or iscsi-scst) 1.0.1.1 and earlier allow remote attackers to cause a denial of service (memory corruption and daemon crash) or possibly execute arbitrary code via (a) a long iSCSI Name string in an SCN message or (b) an invalid PDU.

Ubuntu Security Notice 1156-1 - 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. 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. Various other issues were also addressed.
