Bad range in Snort rules

[Lukas Matt <lukas.matt () sophos com>]

Hey guys,

I ran into following error message "Bad range: 4294967296"
That affect rule 28519 and 28514. The problem here is following part:

   byte_test:4,>,4294967296,18,relative,little;

Under 32bit the maximum Int is 2^32-1 but in the rule you forgot to 
subtract 1.
I checked also the documentation and the maximum for your byte_test is 
4294967295.

Could you double check that?

Cheers,
Lukas
