Security Vulnerability in Firmware for T5220, T5140 and T5240 Systems May Allow a Denial of Service (DoS)
A security vulnerability in the firmware for Sun Netra T5220 systems
and SPARC Enterprise T5140 and T5240 systems may allow a local unprivileged
user to panic the system, which is a type of Denial of Service (DoS).
2. Contributing Factors
This issue can occur on the following platforms: SPARC Platform
- Sun Netra T5220 Server with firmware version 7.1.3 and without patch 136934-03
- SPARC Enterprise T5140 and T5240 Servers with firmware version 7.1.3.c and without patch 136936-06
No other Sun systems are affected by this issue.
To determine the firmware version on the system, log in to the
service processor and run the 'showhost' command as in the
following example (from the T5220):
Sun System Firmware 7.1.3 2008/05/27 09:53
Host flash versions:
Hypervisor 1.6.4 2008/05/27 08:45
OBP 4.28.6 2008/05/23 12:07
POST 4.28.6 2008/05/23 12:32
The system will panic or produce unpredictable results. The panic
string will include "BAD TRAP type=33" or "BAD TRAP type=34".
User applications may fail with a segmentation fault (SIGSEGV) and may
also write a core file, depending on the user's privileges and the
system-wide coreadm(1M) settings.
There is no workaround for this issue. Please see the Resolution
This issue is addressed on the following platforms:
- Sun Netra T5220 Server with firmware version 7.1.4.a (as delivered in patch 136934-03 or later)
- SPARC Enterprise T5140 and T5240 Servers with firmware version 7.1.3.d (as delivered in patch 136936-06 or later)
