Topic

An updated scsi-target-utils package that fixes one security issue 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.

Description

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.

A format string flaw was found in scsi-target-utils' tgtd daemon. A
remote attacker could trigger this flaw by sending a carefully-crafted
Internet Storage Name Service (iSNS) request, causing the tgtd daemon to
crash. (CVE-2010-0743)

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