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. • https://www.exploit-db.com/exploits/21407 ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-02:23.stdio.asc http://archives.neohapsis.com/archives/vulnwatch/2002-q2/0033.html http://online.securityfocus.com/archive/1/268970 http://online.securityfocus.com/archive/1/269102 http://www.ciac.org/ciac/bulletins/m-072.shtml http://www.iss.net/security_center/static/8920.php http://www.kb.cert.org/vuls/id/809347 http://www.osvdb.org/6095 http://www.secu •

fts routines in FreeBSD 4.3 and earlier, NetBSD before 1.5.2, and OpenBSD 2.9 and earlier can be forced to change (chdir) into a different directory than intended when the directory above the current directory is moved, which could cause scripts to perform dangerous actions on the wrong directories. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-01:40.fts.v1.1.asc http://archives.neohapsis.com/archives/netbsd/2001-q3/0204.html http://www.iss.net/security_center/static/8715.php http://www.openbsd.org/errata28.html http://www.osvdb.org/5466 http://www.securityfocus.com/bid/3205 •
