Bug description:posix_getpwnam("") && posix_getgrnam("") didn't return false on
Mac OSX 10.8
Description:
------------
In Mac OS X 10.8 mountain lion, getpwnam() && getgrnam() didn't return
NULL
when empty string supplied. this is a bug of 10.8.0
since uid 0 an gid 0 most belongs to root, this might have security issue.
and this breaks these test cases:
posix_getgrnam(): Basic tests [ext/posix/tests/posix_getgrnam.phpt]
posix_getgrnam(): Basic tests [ext/posix/tests/posix_getgrnam_basic.phpt]
posix_getpwnam(): Basic tests [ext/posix/tests/posix_getpwnam.phpt]
posix_getpwnam(): Basic tests [ext/posix/tests/posix_getpwnam_basic.phpt]
here is reproducible code from: Andreas Fink <[email protected]>:
#include <sys/types.h>
#include <stdio.h>
#include <pwd.h>
#include <uuid/uuid.h>
#include <stdlib.h>
#define MAYBE_NULL_STRING(a) (a ? a : "(NULL)")
extern int errno;
int main(int argc, char *argv[])
{
errno = 0;
struct passwd *pwdstruct = getpwnam("");
printf("errno = %d\n",errno);
if(pwdstruct == NULL)
{
printf("pwdstruct == NULL\n");
exit(0);
}
printf("pw_name: %s\n",MAYBE_NULL_STRING(pwdstruct->pw_name));
printf("pw_passwd: %s\n",MAYBE_NULL_STRING(pwdstruct->pw_passwd));
printf("pw_uid: %d\n",pwdstruct->pw_uid);
printf("pw_gid: %d\n",pwdstruct->pw_gid);
}
produces
$ ./a.out
errno = 0
pw_name:
pw_passwd:
pw_uid: 0
pw_gid: 0
Test script:
---------------
<?php
var_dump(posix_getpwnam(""));
var_dump(posix_getgrnam(""));
Expected result:
----------------
bool(false)
bool(false)
Actual result:
--------------
array(7) {
["name"]=>
string(0) ""
["passwd"]=>
string(0) ""
["uid"]=>
int(0)
["gid"]=>
int(0)
["gecos"]=>
string(0) ""
["dir"]=>
string(0) ""
["shell"]=>
string(0) ""
}
array(4) {
["name"]=>
string(0) ""
["passwd"]=>
string(0) ""
["members"]=>
array(0) {
}
["gid"]=>
int(0)
}
