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. 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.
