[mod-security-users] How to filter this?

[sam w. <sa...@au...>]

Hi,

Recently my website received alot of buffer overflow attacks with the
following content:
1.2.3.4 - - [25/Oct/2004:10:05:34 +0800] "SEARCH
/\x90\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x
02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\ 

x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1 ....
...


The apache has plugins mod_security and mod_filter compiled with.
How can I implement rules to filter the above attack?

Thanks
Sam
