RHSA-2007:0497 - Security Advisory

Topic

Updated iscsi-initiator-utils packages that fix a security flaw in
open-iscsi are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

The iscsi package provides the server daemon for the iSCSI protocol, as
well as the utility programs used to manage it. iSCSI is a protocol for
distributed disk access using SCSI commands sent over Internet Protocol
networks.

Olaf Kirch discovered two flaws in open-iscsi. A local attacker could use
these flaws to cause the server daemon to stop responding, leading to a
denial of service. (CVE-2007-3099, CVE-2007-3100).

All users of open-iscsi should upgrade to this updated package which
resolves these issues.

Note: This issue did not affect Red Hat Enterprise Linux 2.1, 3, or 4.
open-iscsi is available in Red Hat Enterprise Linux 5 as a Technology
Preview.
