Security Vulnerability in Firmware for T5220, T5140 and T5240 Systems May Allow a Denial of Service (DoS)

1. Impact

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

Note: 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):

sc> showhost
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

3. Symptoms

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.

4. Workaround

There is no workaround for this issue. Please see the Resolution section below.

5. Resolution

This issue is addressed on the following platforms:

SPARC Platform

• 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)
