Hi Serdar, The header name buffer overflow looks for a header name > 64 characters. Header names are taken to be the tags in the data header, e.g. Subject: Return-Path: Received: etc. If the number of characters before the ":" is more than 64 characters the smtp preprocessor alerts. The max_header_line_len has nothing to do with this - it looks for the length of the entire line. Is your network asynchronous? Are you dropping packets? Can you provide a pcap that generates the alert (send to bugs () snort org)? Thanks, Todd serdar uzun wrote:
Hi, My Snort alerts many times with "smtp: Attempted header name buffer overflow". Then I cleared the line "max_header_line_len .." in snort.conf. But it has been continueing with same alert.
