Sun(sm) Alert Notification
* Sun Alert ID: 102305
* Synopsis: Security Vulnerability With Sun StorADE Version 2.4
Installation
* Category: Security
* Product: Storage Automated Diagnostic Environment 2.4
* BugIDs: 6397587
* Avoidance: Patch, Workaround
* State: Resolved
* Date Released: 02-Jun-2006
* Date Closed: 02-Jun-2006
* Date Modified:
1. Impact
A local unprivileged user may be able to execute arbitrary code with
the privileges of another user (including root), due to incorrect file
and directory permissions from one of the package components of the
Sun Storage Automated Diagnostic Environment (StorADE) Software.
2. Contributing Factors
This issue can occur in the following release:
SPARC Platform
* Storage Automated Diagnostic Environment (StorADE) 2.4 (for
Solaris 8, 9 and 10) without patch 117654-60
Notes:
1. StorADE versions 2.0, 2.1, 2.2, and 2.3 are not affected by this
issue (2.4 is the only version affected).
2. The x86 platform is not affected by this issue.
3. This issue only affects systems which have installed the optional
SUNWstadm package. The optional SUNWstadm package adds a web
browser-based graphical user interface to the Sun Storage
Automated Diagnostic Environment software.
To determine if the SUNWstadm has been installed on the system, the
following command can be run:
# pkginfo SUNWstadm
SUNWstadm Storage Automated Diagnostic Environment - Management Station UI
To determine the version of StorADE running on a system, the following
command can be run:
# pkginfo -l SUNWstade | grep ^VERSION
VERSION=2.4
3. Symptoms
Files and directories which comprise the optional SUNWstadm package
will have world writable permissions. The files and directories will
be installed under the /var/opt/webconsole/webapps/storade directory
and can be listed via the following find(1) command:
$ find /var/opt/webconsole/webapps/storade -perm -002 -print
4. Relief/Workaround
To work around the described issue prior to patch relief, the
administrator can make the mode changes manually within the active
"Lockhart" directory by running the following commands:
# find /var/opt/webconsole/webapps/storade -type d -exec chmod 755 {} \;
# find /var/opt/webconsole/webapps/storade -type f -exec chmod 644 {} \;
5. Resolution
This issue is addressed in the following release:
SPARC Platform
* Storage Automated Diagnostic Environment (StorADE) 2.4 (for
Solaris 8, 9 and 10) with patch 117654-60 or later

Simultaneous Multi-Threading Processors May Leak Information
5 June 2006
===========================================================================
AusCERT Security Bulletin Summary
---------------------------------
Product: Multi- or Hyper-threading Processors
with shared L1 caches
Publisher: Sun Microsystems
Operating System: Solaris 8, 9 and 10
Impact: Increased Privileges
Access Privileged Data
Access: Existing Account
CVE Names: CAN-2005-0109
Ref: ESB-2005.0385
Original Bulletin:
http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-26-101739-1
- - --------------------------BEGIN INCLUDED TEXT--------------------
Sun(sm) Alert Notification
* Sun Alert ID: 101739
* Synopsis: Simultaneous Multi-Threading Processors May Leak
Information
* Category: Security
* Product: Solaris 9 Operating System, Solaris 10 Operating System,
Solaris 7 Operating System, Solaris 8 Operating System
* BugIDs: 6278935
* Avoidance: Workaround
* State: Resolved
* Date Released: 01-Jun-2005, 01-Jun-2006
* Date Closed: 01-Jun-2006
* Date Modified: 01-Jun-2006
1. Impact
On platforms supporting simultaneous multi-threading (Hyper-Threading
technology), local unprivileged users might be able to deduce
potentially secret data from another executing thread, using cache
eviction analysis techniques.
This issue is described in "Cache Missing for Fun and Profit" by Colin
Percival, at http://www.daemonology.net/papers/htt.pdf.
This issue is referenced by CERT vulnerability note VU#911878 at
http://www.kb.cert.org/vuls/id/911878 and CAN-2005-0109 at
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0109.
2. Contributing Factors
This issue can occur in the following releases:
x86 Platform
* Solaris 7
* Solaris 8
* Solaris 9
* Solaris 10
Notes:
1. This issue occurs only on processor platforms supporting
simultaneous multi-threading (Hyper-Threading technology) with
shared L1 caches.
2. Solaris on AMD Multi-Core processors is not affected by this
issue.
3. Solaris on the SPARC platform is not affected by this issue.
4. While an exploit has been demonstrated in a controlled
environment, this vulnerability requires local access. The victim
thread's codepaths should be well understood by the attacker.
3. Symptoms
There are no predictable symptoms that would indicate the above
described issue has been exploited.
4. Relief/Workaround
Relief for this issue can be achieved by following methods:
A) Disabling Hyper-Threading in the BIOS:
Many BIOS implementations provide a way to disable the Hyper-Threading
feature. With the feature disabled, threads will not be able to
simultaneously execute on a given physical processor, thus closing the
vulnerability.
Note: Overall system performance will likely be impacted.
OR:
B) Dynamic CPU Off-lining:
Solaris provides a mechanism allowing CPUs (including virtual on
multi-threaded cores) to be taken off-line without rebooting. By
taking virtual CPUs off-line, a multi-threaded (e.g. Hyper-Threaded)
processor can be forced to support only one thread at a time. This
restriction greatly reduces the ability of the spy to effectively
monitor the victim by forcing context switching to occur between
thread/processes. CPUs may be taken off-line with the psradm(1M)
command.
Note: Overall system performance will likely be impacted, and these
settings will not persist across reboot.
Example: Off-lining all but one of each physical processor's logical
CPUs:
# psrinfo -vp
The physical processor has 2 virtual processors (0, 4)
x86 (chipid 0x0 GenuineIntel family 15 model 2 step 6 clock 3000 MHz)
Intel(r) Xeon(tm) MP CPU 3.00GHz
The physical processor has 2 virtual processors (1, 5)
x86 (chipid 0x1 GenuineIntel family 15 model 2 step 6 clock 3000 MHz)
Intel(r) Xeon(tm) MP CPU 3.00GHz
The physical processor has 2 virtual processors (2, 6)
x86 (chipid 0x2 GenuineIntel family 15 model 2 step 6 clock 3000 MHz)
Intel(r) Xeon(tm) MP CPU 3.00GHz
The physical processor has 2 virtual processors (3, 7)
x86 (chipid 0x3 GenuineIntel family 15 model 2 step 6 clock 3000 MHz)
Intel(r) Xeon(tm) MP CPU 3.00GHz
# psrinfo

5 off-line since 05/18/2005 11:05:07
6 off-line since 05/18/2005 11:05:07
7 off-line since 05/18/2005 11:05:07
Note: Availability of the psrinfo(1M) physical processor view (-vp) in
Solaris 9 requires kernel patch 117172-17 or later. The feature is
not available in Solaris 8 and earlier releases.
OR:
C) Solaris Containers:
Properly configured, the Containers feature in Solaris 10 can be used
to close this vulnerability. Containers in Solaris consist of Resource
Pools and Zones.
The Zones (zones(5)) feature allows for the creation of multiple
virtual Solaris environments. Administrators can configure zones to
contain users and applications. Each zone can then be bound to a CPU
resource pool configured as above. Users and applications in a given
zone will only be able to execute on CPUs contained in that zone's
pool, thus preventing communication/spying across zones. It should be
noted that proper use of Resource Pools to isolate CPU use of
potential spy threads from processes containing valuable secret data
(such as private keys) on the system could address this vulnerability.
However, using Zones in addition to Resource Pools provides additional
isolation since applications/users inside a given zone cannot see
other applications/users outside the zone virtual environment.
Note: The above workaround applies only to systems with more than one
physical processor.
Resource Pools are available in Solaris 9 as part of the built-in
Solaris Resource Manager software. Zones and Resource Pools are both
available in Solaris 10 as part of the built-in Solaris Containers
feature.
For more information about using Zones, please visit the "Zones
BigAdmin System Administration Portal"
at http://www.sun.com/bigadmin/content/zones/
For more information about using Zones with Resource Pools, please see
the "Solaris Containers Resource Management and Solaris Zones"
answerbook at http://docs.sun.com/app/docs/doc/817-1592.
5. Resolution
Workarounds described in the "Relief/Workaround" section are
considered as the only practical methods to mitigate this issue.
