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.

According to the versions of the scsi-target-utils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - 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.(CVE-2010-2221)

  - Multiple format string vulnerabilities in isns.c in (1)     Linux SCSI target framework (aka tgt or     scsi-target-utils) 1.0.3, 0.9.5, and earlier and (2)     iSCSI Enterprise Target (aka iscsitarget) 0.4.16 allow     remote attackers to cause a denial of service (tgtd     daemon crash) or possibly have unspecified other impact     via vectors that involve the isns_attr_query and     qry_rsp_handle functions, and are related to (a) client     appearance and (b) client disappearance     messages.(CVE-2010-0743)

This update of iscscitarget/tgt fixes multiple overflows and a format string vulnerability :

  - CVE-2010-2221: CVSS v2 Base Score: 5.0 (MEDIUM)     (AV:N/AC:L/Au:N/C:N/I:N/A:P): Buffer Errors (CWE-119)

  - CVE-2010-0743: CVSS v2 Base Score: 5.0 (MEDIUM)     (AV:N/AC:L/Au:N/C:N/I:N/A:P): Format String     Vulnerability (CWE-134)

The remote Oracle Linux 5 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2010-0518 advisory.

    [0.0-6.20091205snap.3]
    - Fix buffer overflow in isns scn handling (CVE-2010-2221)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

An updated scsi-target-utils package that fixes multiple security issues is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The scsi-target-utils package contains the daemon and tools to set up and monitor SCSI targets. Currently, iSCSI software and iSER targets are supported.

Multiple buffer overflow flaws were found in scsi-target-utils' tgtd daemon. A remote attacker could trigger these flaws by sending a carefully-crafted Internet Storage Name Service (iSNS) request, causing the tgtd daemon to crash. (CVE-2010-2221)

Red Hat would like to thank the Vulnerability Research Team at TELUS Security Labs and Fujita Tomonori for responsibly reporting these flaws.

All scsi-target-utils users should upgrade to this updated package, which contains a backported patch to correct these issues. All running scsi-target-utils services must be restarted for the update to take effect.

All running scsi-target-utils services must be restarted for the update to take effect.

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. (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.

This update of tgt fixes multiple overflows and a format string vulnerability :
