An updated scsi-target-utils package that fixes one security issue is now available for Red Hat Enterprise Linux 5 and 6.
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.
A double-free flaw was found in scsi-target-utils’ tgtd daemon. A remote attacker could trigger this flaw by sending carefully-crafted network traffic, causing the tgtd daemon to crash. (CVE-2011-0001)
Red Hat would like to thank Emmanuel Bouillon of NATO C3 Agency for reporting this issue.
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.
