Cross-site scripting (XSS) vulnerability in NetWin Surgemail before 4.3g allows remote attackers to inject arbitrary web script or HTML via the username_ex parameter to the surgeweb program.

Stack-based buffer overflow in the _lib_spawn_user_getpid function in (1) swatch.exe and (2) surgemail.exe in NetWin SurgeMail 38k4 and earlier, and beta 39a, allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via an HTTP request with multiple long headers to webmail.exe and unspecified other CGI executables, which triggers an overflow when assigning values to environment variables. NOTE: some of these details are obtained from third party information.

Format string vulnerability in webmail.exe in NetWin SurgeMail 38k4 and earlier and beta 39a, and WebMail 3.1s and earlier, allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via format string specifiers in the page parameter.
