Description:
|
| 3 |
The chrp_show_cpuinfo function (chrp/setup.c) in Linux kernel 2.4.21
|
| 4 |
through 2.6.18-53, when running on PowerPC, might allow local users
|
| 5 |
to cause a denial of service (crash) via unknown vectors that cause
|
| 6 |
the of_get_property function to fail, which triggers a NULL pointer
|
| 7 |
dereference.

Ubuntu-Description:
|
| 11 |
It was discovered that PowerPC kernels did not correctly handle reporting
|
| 12 |
certain system details. By requesting a specific set of information,
|
| 13 |
a local attacker could cause a system crash resulting in a denial
|
| 14 |
of service.

Notes:
|
| 16 |
jmm> This appears more of a regular bug with a specific piece of hw
|
| 17 |
jmm> than a security problem. Do we support the chrp POWER platform?
