Improperly validated user-supplied input to the Content-Type header can create an overflow condition.
|
|
|
|
As a result, excessive data copied onto the stack can overwrite critical parts of the stack frame such as the calling functions' return address, potentially allowing remote code execution with the privileges of the webserver.
