The overwrite happens before any ACL/community checks. There just needs an SNMP port to be configured. The off-by-one happens on the heap, as buf is declared static. So depending on your compiler organizing the .bss this might be better or worse than being placed on the stack. :) More info and a patch is here: https://bugzilla.novell.com/show_bug.cgi?id=895773 Sebastian -- ~ perl self.pl ~ $_='print"\$_=\47$_\47;eval"';eval ~ krahmer@...e.de - SuSE Security Team
