Bug description:
[Impact]
[From https://code.google.com/p/google-security-research/issues/detail?id=758
]
A recent refactoring cof this codepath
(https://github.com/torvalds/linux/commit/2e4e6a17af35be359cc8f1c924f8f198fbd478cc)
introduced an integer overflow in xt_alloc_table_info, which on 32-bit
systems can lead to small structure allocation and a copy_from_user
based heap corruption.
More specifically, the overflow may have been introduced in
https://github.com/torvalds/linux/commit/711bdde6a884354ddae8da2fcb495b2a9364cc90
; specifically the bit:
+ size_t sz = sizeof(*info) + size;
(where size is an unsigned int passed from userspace).
This issue should only affect 32bit platforms (xt_table_info.size is
an unsigned int).
[Fix]
Upstream proposed fix:
http://marc.info/?l=netfilter-devel&m=145757136822750&w=2
[Test Case]
Download v4 code from:
https://code.google.com/p/google-security-research/issues/detail?id=758
gcc *v4.c -o v4
./v4
Your machine should _not_ crash. This only affects 32-bit kernels
