Bug #58723 Incorrect while loop increment in uploadprogress.c
Submitted: 2009-06-15 16:58 UTC Modified: 2009-06-16 01:43 UTC
From: terralith at yahoo dot com Assigned:
Status: Closed Package: uploadprogress (PECL)
PHP Version: 5.2.9 OS: CentOS 5
Private report: No CVE-ID: None

Description:
------------
In HEAD (rev 1.21) of uploadprogress.c, in uploadprogress_file_php_get_info(), it seems that one of the whitespace-skip loops is incrementing the wrong pointer variable.

Reproduce code:
---------------
Lines 402-403:
----------
/* trim spaces in front of the name/value */
while (*k && *k <= 32) v++;
----------


Should be:
----------
/* trim spaces in front of the name/value */
while (*k && *k <= 32) k++;
----------

Expected result:
----------------
Whitespace at the beginning of each key and value gets skipped/ignored.

Actual result:
--------------
If the key contains leading whitespace, a possibility for an infinite loop exists.

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

Thanks for your patch. I will release 1.0.1 soon.
