Date:	01/23/2012
Bugs:	#314187
ID:	201201-06

Synopsis

Format string vulnerabilities in iSCSI Enterprise Target could result in execution of arbitrary code or a Denial of Service.

Background

iSCSI Enterprise Target is an open source iSCSI target with professional features.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
sys-block/iscsitarget	< 1.4.19	>= 1.4.19	All supported architectures

Description

Multiple functions in usr/iscsi/isns.c of iSCSI Enterprise Target contain format string errors.

Impact

A remote attacker could send a specially-crafted Internet Storage Name Service (iSNS) request, possibly resulting in the execution of arbitrary code with root privileges or cause a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All iSCSI Enterprise Target users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-block/iscsitarget-1.4.19"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since August 11, 2010. It is likely that your system is already no longer affected by this issue.
