IBM AIX 5.3 does not properly verify the status of file descriptors before setuid execution, which allows local users to gain privileges by closing file descriptor 0, 1, or 2 and then invoking a setuid program, a variant of CVE-2002-0572.

HP HP-UX B11.11 does not properly verify the status of file descriptors before setuid execution, which allows local users to gain privileges by closing file descriptor 0, 1, or 2 and then invoking a setuid program, a variant of CVE-2002-0572.

Sun Solaris 9 does not properly verify the status of file descriptors before setuid execution, which allows local users to gain privileges by closing file descriptor 0, 1, or 2 and then invoking a setuid program, a variant of CVE-2002-0572.

FreeBSD 4.5 and earlier, and possibly other BSD-based operating systems, allows local users to write to or read from restricted files by closing the file descriptors 0 (standard input), 1 (standard output), or 2 (standard error), which may then be reused by a called setuid process that intended to perform I/O on normal files.
