Red Hat: RHSA-2011:0332-01 Critical: scsi-target-utils Remote Crash

Scroller Redhat
Important enhancement for scsi-target-utils in Red Hat versions 5 and 6 addresses the risk of remote crashes successfully through a newly released update.
An updated scsi-target-utils package that fixes one security issue is now available for Red Hat Enterprise Linux 5 and 6

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Summary

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.
