CRITICAL:
Moderately critical

IMPACT:
DoS, System access

TFTP Server SP 1.x
http://secunia.com/product/18058/

DESCRIPTION:
Mati Aharoni has discovered a vulnerability in TFTP Server SP, which
can be exploited by malicious people to cause a DoS (Denial of
Service) or compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the handling
of filenames and can be exploited to cause a stack-based buffer
overflow via a read or write request with an overly long filename.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in the Windows version of TFTP Server
SP version 1.4. Other versions may also be affected.

SOLUTION:
Restrict network access to the TFTP service.
