A remote overflow exists in MailEnable's Messaging Services when logging is enable, which occurs by default. An attacker could send an HTTP get request of 4045 bytes or more, causing a heap-based buffer overflow. An attacker could use this to execute arbitrary code on the vulnerable system, or simply crash the application, causing a denial of service. When logging is not enabled, the HTTP request size must be at least 8500 bytes.
