No, I think that's it.
But watch out if you have kernels older than 2.6.28, the above patches
don't apply there properly. I have released a 2.6.27.52-rc3 with them
reworked, but I don't really feel comfortable with it at the moment, so
any help and testing would be greatly appreciated.

Думаю дождаться 2.6.27.52, атака на терминал чревата максимум доступом в локальную сеть с правами root (и к примонтированным флэшкам-сидюшкам). Если получится раньше, попробую прикрутить SUSE'шный патч, хотя что-то подсказывает, что быстрее выйдет 2.6.27.y. Спасибо! Дождался. kernel-image-tmc-tc-2.6.27-alt10 -> sisyphus: * Sat Aug 21 2010 Michael Shigorin <mike@altlinux> 2.6.27-alt10 - 2.6.27.52: fixes local root vulnerability CVE-2010-2240 (kernel: mm: keep a guard page below a grow-down stack segment) + thanks ldv@ for convenient support (closes: #23914) |
