Operating system: rh-9
PHP version: 4.3.6
PHP Bug Type: Compile Warning
Bug description: improper C type conversion in
php-4.3.6/ext/standard/var_unserialize.c line 310
Description:
------------
Need a explicit type cast...
original source:
if(yych <= '\277') goto yy15;
patched:
if(yych <= (YYCTYPE)'\277') goto
yy15;
Reproduce code:
---------------
http://barajas.mit.edu/php_bug/test.php.txt
// just the relevant bits here - see url for a working program
<?php if (isSet($_POST["submit"])) print_r($_POST["a"]); ?>
<form method = "post" action = "">
<input type = "hidden" name = "a[]" value = "val1">
<input type = "hidden" name = "a[]" value = "val2">
<input type = "hidden" name = "a[]" value = "val3">
<input type = "submit" name = "submit" value = "submit">
</form>
Expected result:
----------------
The array $_POST["a"] should have three strings in it after the form is
submitted. Unpatched PHP-4.3.6 would repeat the last two values in
additional two array slots. Forms submitted via get didn't exhibit this
behavior. Scalars passed via post also did not exhibit this behavior.
After I patched the C code as above, I got three and only three strings
back in $_POST["a], which is what I'd expect.
Actual result:
--------------
Array ( [0] => val1 [1] => val2 [2] => val3 [3] => val2 [4] => val3)
