| 标题 | RICOH SP 221 V1.02 Denial of Service |
|---|
| 描述 | An HTTP multipart/form-data parser in the analyzed RICOH SP 221 firmware enters an infinite loop when a multipart part header is not terminated by a newline. After the parser fails to find the expected newline, it returns to the same loop with an unchanged input cursor. A malformed HTTP request can therefore keep the HTTP request-processing task executing indefinitely and cause a denial of service. |
