RHSA-2010:0518 - Security Advisory

Topic

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.

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.

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.
