Ac1dB1tch3z Vs Linux Kernel x86_64 0day
Today is a sad day..
R.I.P.
Tue, 29 Apr 2008 / Tue, 7 Sep 2010
a bit of history:
MCAST_MSFILTER Compat mode bug found... upon commit! (2 year life on this one)
author David L Stevens <dlstevens@us.ibm.com>
Tue, 29 Apr 2008 10:23:22 +0000 (03:23 -0700)
committer David S. Miller <davem@davemloft.net>
Tue, 29 Apr 2008 10:23:22 +0000 (03:23 -0700)
This patch adds support for getsockopt for MCAST_MSFILTER for
both IPv4 and IPv6. It depends on the previous setsockopt patch,
and uses the same method.
Signed-off-by: David L Stevens <dlstevens@us.ibm.com>
Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
Signed-off-by: David S. Miller <davem@davemloft.net>
------------------------------------------------------------
Thank you for signing-off on this one guys.
This exploit has been tested very thoroughly
over the course of the past few years on many many targets.
Thanks to redhat for being nice enough to backport it into early
kernel versions (anything from later August 2008+)
Ac1dB1tch3z would like to say FUCK YOU Ben Hawkes. You are a new hero! You saved the
plan8 man. Just a bit too l8.
PS:
OpenVZ Payload / GRsec bypass removed for kidiots and fame whores. (same thing right ;))

/* enlightenment 200912092327
enlightenment is an exploitation framework mostly geared towards the
exploitation of null ptr dereference bugs, though its routines are
applicable to overflows and other bugclasses as well. It's a public
demonstration of the capabilities of kernel exploits, useful for
commercial pentesting or verifying the security of your own systems.
enlightenment supports:
all kernels 2.4 and 2.6 (both x86 and x64)
setting *uid/*gid 0
clearing supplementary groups
raising to full capabilities
pre and post cred structures
cloning of init's cred structure (when no cred symbols are present)
CONFIG_DEBUG_RODATA bypass (both old and new versions)
xen hypercalls for .text modification on new DEBUG_RODATA under Xen
SELinux execmod/execmem bypassing
SELinux disabling (and faking continued enforcement)
even if the toggling variable has no generated symbol
IMA disabling (rendering its TPM-based integrity checks worthless)
Apparmor disabling
Auditing disabling
Tomoyo disabling
generic LSM disabling
all public methods of bypassing mmap_min_addr
pearls of wisdom from some of the greatest writers and thinkers of
the past couple centuries :)
To create your own exploit module for enlightenment, just name it
exp_whatever.c
It will be auto-compiled by the shell script and thrown into
the list of loaded exploit modules
if you want to use the list of non-NULL exploits:
./run_nonnull_exploits.sh
if you want to run the list of NULL ptr deref exploits:
./run_null_exploits.sh
Each module must have the following features:
It must include this header file, exp_framework.h
A description of the exploit, the variable being named "desc"
A "prepare" function: int prepare(unsigned char *ptr)
where ptr is the ptr to the NULL mapping, which you are able to write to
This function can return the flags described below for prepare_the_exploit
Return 0 for failure otherwise
A "trigger" function: int trigger(void)
Return 0 for failure, nonzero for success
A "post" function: int post(void)
This function can return the flags described below for post_exploit
A "requires_null_page" int: int requires_null_page;
This should be 1 if a NULL page needs to be mapped, and 0 otherwise
(if you want to use the framework to exploit non-NULL ptr bugs)
A "get_exploit_state_ptr" function:
int get_exploit_state_ptr(struct exploit_state *ptr)
Generally this will always be implemented as:
struct *exp_state;
int get_exploit_state_ptr(struct exploit_state *ptr)
{
exp_state = ptr;
return 0;
}
It gives you access to the exploit_state structure listed below,
get_kernel_sym allows you to resolve symbols
own_the_kernel is the function that takes control of the kernel
(in case you need its address to set up your buffer)
the other variables describe the exploit environment, so you can
for instance, loop through a number of vulnerable socket domains
until you detect ring0 execution has occurred.
That's it!

/* sieve (because the Linux kernel leaks like one, get it?)
Bug NOT discovered by Marcus Meissner of SuSE security
This bug was discovered by Ramon de Carvalho Valle in September of 2009
The bug was found via fuzzing, and on Sept 24th I was sent a POC DoS
for the bug (but had forgotten about it until now)
Ramon's report was sent to Novell's internal bugzilla, upon which
some months later Marcus took credit for discovering someone else's bug
Maybe he thought he could get away with it ;) Almost ;)
greets to pipacs, tavis (reciprocal greets!), cloudburst, and rcvalle!
first exploit of 2010, next one will be for a bugclass that has
afaik never been exploited on Linux before
note that this bug can also cause a DoS like so:

/* random notes I took when writing this (all applying to the 64bit case):
checking in a bitmap based on node_states[2] or node_states[3]
(former if HIGHMEM is not present, latter if it is)
each node_state is of type nodemask_t, which is is a bitmap of size
MAX_NUMNODES/8
RHEL 5.4 has MAX_NUMNODES set to 64, which makes this 8 bytes in size
so the effective base we're working with is either node_states +
16 or node_states + 24
on 2.6.18 it's based off node_online_map
node_isset does a test_bit based on this base
so our specfic case does: base[ourval / 8] & (1 << (ourval & 7))
All the calculations appear to be signed, so we can both index in
the negative and positive direction, based on ourval
On 64bit, this gives us a 256MB range above and below our base to
grab memory of (by passing in a single page and a single node for
each bit we want to leak the value of, we can reconstruct entire bytes)
We can determine MAX_NUMNODES by looking up two adjacent numa bitmaps,
subtracting their difference, and multiplying by 8 but we don't need
to do this.

* win95ping.c
*
* Simulate the evil win95 "ping -l 65510 buggyhost".
* version 1.0 Bill Fenner <fenner@freebsd.org> 22-Oct-1996
* version 1.01 Mike Bremford <Mike.Bremford@bl.uk> patched for Linux
* version 1.02 Barak Pearlmutter <bap@sloan.salk.edu> clean compile
*
* This requires raw sockets that don't mess with the packet at all (other
* than adding the checksum). That means that SunOS, Solaris, and
* BSD4.3-based systems are out. BSD4.4 systems (FreeBSD, NetBSD,
* OpenBSD, BSDI) will work. Linux might work, I don't have a Linux
* system to try it on.

*
* Linux Kernel <= 2.6.31-rc5 sigaltstack 4-Byte Stack Disclosure
* Jon Oberheide <jon@oberheide.org>
* http://jon.oberheide.org
*
* Updated by Steve Beattie and Kees Cook
*
* Information:
*
* CVE-2009-2847
* https://bugzilla.redhat.com/show_bug.cgi?id=515392
*
* http://git.kernel.org/linus/0083fc2c50e6c5127c2802ad323adf8143ab7856
*
* Ulrich Drepper correctly points out that there is generally padding in
* the structure on 64-bit hosts, and that copying the structure from
* kernel to user space can leak information from the kernel stack in those
* padding bytes.
*
* Notes:
*
* Only 4 bytes of uninitialized kernel stack are leaked in the padding
* between stack_t's ss_flags and ss_size. The disclosure only affects
* affects 64-bit hosts.
