Hi everybody, unfortunately today a new root exploit appeared.
Look at: http://sota.gen.nz/compat2/
After some tests I can say: It works on Archlinux and Ubuntu, but not on debian.
The "bugfix" found on http://seclists.org/fulldisclosure/2010/Sep/273 does not work on Arch and Ubuntu.
There's actually two holes with two exploits. This workaround is for the 'compat1' exploit - which doesn't work on Arch, unlike compat2, which works. If I understand this right, the following three patches fix the problems: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdif... http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff&h=c41d68a513c71e35a14f66d71782d27a79a81ea6 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdif... I am building a new 64 Bit kernel26 right now, but I don't know when I can push this to the repositories, hopefully some time tonight.
