SlimFTPd is prone to a remote denial of service vulnerability. This issue is due to a failure in the application to handle exceptional conditions.
|
|
|
|
The problem presents itself during login. The application fails to handle malicious input in a proper manner resulting in a crash of the server, thus denying service to legitimate users.
