A Security Vulnerability in the Sun System Firmware on Certain SPARC Systems May Allow Unauthorized Data Access
1. Impact
A security vulnerability in the firmware for certain Sun SPARC Systems using the Sun UltraSPARC T1, UltraSPARC T2, and UltraSPARC T2+ processors may
allow unauthorized data access, where local privileged users in one
Logical Domain (ldm(1M)) may be able to gain access to
memory in another logical domain.
2. Contributing Factors
This issue can occur on the following platforms (when running multiple
domains):
- Sun SPARC Enterprise T5140/T5240 running Sun System Firmware
7.1.3.d or 7.1.3.e
- Sun Netra T5220 running Sun System Firmware 7.1.3
- Sun SPARC Enterprise T5120/T5220 running Sun System Firmware
7.1.3.d or 7.1.3.e
- Sun Blade T6320 running Sun System Firmware 7.1.3.d or 7.1.3.e
- Sun Fire / SPARC Enterprise T2000 running Sun System Firmware
6.6.3, 6.6.4 or 6.6.5
- Sun Fire / SPARC Enterprise T1000 running Sun System Firmware
6.6.3, 6.6.4 or 6.6.5
- Sun Netra T2000 running Sun System Firmware 6.6.3, 6.6.4 or 6.6.5
- Sun Netra CP3060 running Sun System Firmware 6.6.3, 6.6.4 or 6.6.5
- Sun Blade T6300 running Sun System Firmware 6.6.3, 6.6.4 or 6.6.5
Note 1: No other Sun
systems are affected by this issue.
Note 2: This issue can only occur on systems (listed above) running multiple domains.
Note 3: To determine the
Sun System Firmware version installed on a system, you can query from
the Service Processor command line interface with the following
commands:
ILOM CLI: "show /HOST"
(SysFW 7.x only)
ALOM CLI: "showhost" (SysFW 7.x and
6.x)
Example 1: (look
for "Sun System Firmware" version information underneath the
"Properties" section)
-> show /HOST
/HOST
Targets:
.
.
Properties:
.
.
sysfw_version = Sun System Firmware 7.1.6.d 2008/09/15 17:11
Example 2:
sc> showhost
Sun System Firmware 7.1.6.d 2008/09/15 17:11
Host flash versions:
Hypervisor 1.6.7.a 2008/08/30 05:18
OBP 4.29.0.a 2008/09/15 12:01
POST 4.29.0.a 2008/09/15 12:27
sc>
Note 4: To determine if the
system is running multiple domains, and is therefore potentially
vulnerable, the LDoms Manager package (SUNWldm(1M)) includes a command
to list the domains:
Example 1: This
is a single-domained system:
# /opt/SUNWldm/bin/ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-c-- SP 64 65408M 11% 57m
Example 2: This
is a multi-domained system with the 2nd domain active.
# /opt/SUNWldm/bin/ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 32 2G 1.0% 8m
foo active -t---- 5000 16 2G 6.2% 0s
Example 3: This
is a multi-domained system with the 2nd domain quiesced:
# /opt/SUNWldm/bin/ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 32 2G 57% 11m
foo inactive ------ 16 2G
3. Symptoms
There are no predictable symptoms to indicate this issue has been
exploited to gain unauthorized data access to the system.
4. Workaround
To work around the described issue until the resolution patches can be
applied, restrict privileged access only to trusted users.
5. Resolution
This issue is addressed for these platforms in
the following releases:
- Sun SPARC Enterprise T5140/T5240 Sun System
Firmware 7.1.6 (as delivered in patch 136936-07 or later)
- Sun Netra T5220 Sun System Firmware 7.1.4.a
