Bug #36806 iconv_mime_decode case-sensitivity for encoding token ('B' or 'Q')
Submitted: 2006-03-20 21:42 UTC Modified: 2006-03-21 09:27 UTC
From: jgoldsmith at returnpath dot net Assigned:
Status: Closed Package: ICONV related
PHP Version: 5.1.2 OS: FC4
Private report: No CVE-ID: None

iconv_mime_decode doesn't recognize lower-case encoding tokens  ('b' or 'q'). These are acceptible according to the MIME RFC (

Here is a fix. Edit file: /ext/iconv/iconv.c

Line: 1398
case 'B':
case 'B': case 'b':

Line 1403
case 'Q':
case 'Q': case 'q':

Reproduce code:
$string = '=?UTF-8?b?VGhpcyBpcyBhbiBlbmNvZGVkIHN0cmluZyE=?=';
echo iconv_mime_decode($string,1);

Expected result:
This is an encoded string!

Actual result:
Warning: iconv_mime_decode() [function.iconv-mime-decode]: Malformed string
