Hard link and possibly symbolic link following vulnerabilities in QNX RTOS 4.25 (aka QNX4) allow local users to overwrite arbitrary files via (1) the -f argument to the monitor utility, (2) the -d argument to dumper, (3) the -c argument to crttrap, or (4) using the Watcom sample utility.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
