This signature detects attempts to exploit a known vulerability against HTTP header for known web servers. Using a malicious HTTP client, attackers can send a maliciously crafted request that contains an empty Range or Connection header field to a Web server to crash the Web server daemon; the system must be manually restarted to restore service.
Remote attackers can exploit this vulnerability to crash an affected server, causing a denial of service.
