A vulnerability has been discovered in the HP-UX 11 ftpd daemon. The problem can be triggered using the FTP REST command. By specifying a specially calculated numeric argument to the command, it is possible to disclose the contents of that numeric location in process memory. This issue may be exploited to disclose the contents of sensitive files, such as /etc/passwd.
