hey security team, |
| 11 |
|
|
Its likely that kernel-image-2.6.8-ia64 (2.6.8-12) will be the version |
| 12 |
|
|
that ships in sarge. This kernel has CONFIG_PREEMPT enabled, which has |
| 13 |
|
|
at least one known issue in ptrace code that lets an unpriveleged |
| 14 |
|
|
userspace process trigger an oops. This issue went away upstream by |
| 15 |
|
|
2.6.9, but its unclear what actually fixed it. SuSE/RedHat disable |
| 16 |
|
|
PREEMPT for ia64 (or so I'm told), so they are not affected. This same |
| 17 |
|
|
test case does _not_ fail on x86, which also has PREEMPT enabled for |
| 18 |
|
|
sarge. |
| 19 |
|
|
. |
| 20 |
|
|
This issue has been known for a while, but I waited until after d-i |
| 21 |
|
|
RC3 to upload it, since it changes the ABI. This fix is in the 2.6.8-13 |
| 22 |
|
|
build in unstable, but the release team is blocking this kernel from |
| 23 |
|
|
normal sarge propagation to keep the kernel udebs in sync. |
