23 | * Be proud that perl(1) may proclaim: | |
24 | * Setuid Perl scripts are safer than C programs ... | |
25 | * Do not abandon (deprecate) suidperl. Do not advocate C wrappers. | |
26 | * | |
27 | * The flow was: perl starts, notices script is suid, execs suidperl with same | |
28 | * arguments; suidperl opens script, checks many things, sets itself with | |
29 | * right UID, execs perl with similar arguments but with script pre-opened on | |
30 | * /dev/fd/xxx; perl checks script is as should be and does work. This was | |
31 | * insecure: see perlsec(1) for many problems with this approach. | |
32 | * | |
33 | * The "correct" flow should be: perl starts, opens script and notices it is | |
34 | * suid, checks many things, execs suidperl with similar arguments but with | |
35 | * script on /dev/fd/xxx; suidperl checks script and /dev/fd/xxx object are | |
36 | * same, checks arguments match #! line, sets itself with right UID, execs | |
37 | * perl with same arguments; perl checks many things and does work. | |
38 | * | |
39 | * (Opening the script in perl instead of suidperl, we "lose" scripts that | |
40 | * are readable to the target UID but not to the invoker. Where did | |
41 | * unreadable scripts work anyway?) | |
42 | * | |
43 | * For now, suidperl and perl are pretty much the same large and cumbersome | |
44 | * program, so suidperl can check its argument list (see comments elsewhere). | |
