Description

 A remote overflow exists in WvTftp. WvTftp fails to perform boundary checking on TFTP packet option name value pairs in the wvtftpserver.cc WvTFTPServer::new_connection() function, resulting in a heap overflow. With a specially crafted request, an attacker can remotely execute arbitrary code with root privileges resulting in a loss of integrity.
