Description:
Parvez Anwar has discovered a vulnerability in D-Link TFTP Server, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the handling of read or write requests. This can be exploited to cause a heap-based buffer overflow via an overly long (greater than 272 bytes) file name in a read or write request.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 1.0. Other versions may also be affected.
Solution:
Use in a trusted network environment only.
