Description:
Some vulnerabilities have reported in SmarterMail, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An error exists within the HTTP request handling in SmarterMail Web Server (SMWebSvr.exe), which can be exploited to terminate the service by sending e.g. an overly long GET, HEAD, PUT, POST, or TRACE request.
2) An error exists within the handling of malformed HTTP requests in the SmarterMail Web Server (SMWebSvr.exe). This can be exploited to crash an affected server via incomplete HTTP requests, or via HTTP requests containing special characters.
The vulnerabilities are reported in version 5.0.2999. Other versions may also be affected.
