Overview

Affected versions of this package are vulnerable to Information Exposure via the TFTP transfer process. An attacker can obtain sensitive information by manipulating the server's response to a download request, causing the client to transmit residual data from previous operations when a persistent connection handle is reused. This is only exploitable if a persistent library handle is reused across unrelated operations, such as an upload followed by a TFTP download from an untrusted server.
