[Bug 1083824] [NEW] php5 UTF-8 bug

[Procion]

Public bug reported:

Linux servername 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:33:09 UTC

Bug found, when using pho5-fpm:

Package: php5-fpm
Status: install ok installed
Priority: optional
Section: php
Installed-Size: 8081
Maintainer: Ubuntu Developers <ubuntu-devel-discuss at lists.ubuntu.com>
Architecture: amd64
Source: php5
Version: 5.3.10-1ubuntu3.4
Provides: phpapi-20090626
Depends: libbz2-1.0, libc6 (>= 2.15), libdb5.1, libpcre3 (>= 8.10), libssl1.0.0 (>= 1.0.0), libxml2 (>= 2.7.4), zlib1g (>= 1:1.1.4), mime-support, php5-common (= 5.3.10-1ubuntu3.4), libmagic1, ucf, tzdata
Pre-Depends: dpkg (>= 1.15.7.2~)
Suggests: php-pear


Php application receives registration form with two fields (Name,
Surname) in ru_RU UTF-8. I've checked content of $_REQUEST and $_POST,
and there array 'client', which contains fields with normal valid UTF-8
strings. But then developer of application getting 'client' array to
separate array variable:

$c = $_POST['client'];

and $c then contains invalid UTF-8 sequences.

for example in source was d180d0b8
but in $c it becomes f180d0b8
as you can see, it's invalid sequence and invalid behaviour of php.

and then database engine gives error about that.

I solved issue by getting values directly:

$data = array(
                        'name' => $_POST['client']['name'],
                        'sur_name' => $_POST['client']['surName'],
)

and it works. But the bug still remains and may cause lots of problems.
