Description:
liuqx has discovered a vulnerability in TFTPD32, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error when processing files with overly long file names (greater than 235 bytes). This can be exploited to crash the server via a specially crafted GET or PUT request.
Successful exploitation requires:
* PUT - file exists on the client
* GET - file exists on the server
The vulnerability is confirmed in version 3.01. Other versions may also be affected.
