TFTP: OpenTFTP Server Error Packet Handling Buffer Overflow
This signature detects attempts to exploit a known vulnerability against the OpenTFTP Server. A successful attack can lead to arbitrary code execution.
Extended Description
TFTP Server is prone to a buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied data before storing it in a finite-sized buffer. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. TFTP Server SP 1.4 running on Windows is vulnerable; other versions may also be affected.
