PHP 4.4.6 Segfault with PCRE 7.0 not with 6.6

Infomaniak_Network_S · Avril 20, 2007, 10:32

EN

After upgrading PHP from 4.4.4 to 4.4.6 our customers using
SPIP, Joomla Mambot, etc. their websites display a blank page
or 500 due to a segfault of PHP.

I have backported PCRE from version 7.0 to 6.6 on PHP 4.4.6.
No more segfault of PHP and SPIP works as before.

Après la mise à jour de PHP de 4.4.4 vers 4.4.6
nos clients utilisant SPIP, Joomla Mambot, etc.
on vu leur sites affichaient une page blanche ou une
erreur 500 causé par un segfault de PHP.

J’ai fait un patch pour repasser de la version 7.0 à la 6.6
de la lib PCRE dans PHP 4.4.6. Depuis plus aucun plantage
de PHP et SPIP refonctionne comme avant.

Hi,

I've tried the regexes you mention, but I couldn't reproduce any crash. We need a short reproducing script (e.g. the regex + sample data that makes it crash). Anyway this isn't a bug (if any) in PHP, but rather in PCRE, so you should get that short reproducing script and contact the PCRE authors (pcre-dev@exim.org). I'm also on that ML.

Regards,
Nuno

SPIP has been patched to avoid that PHP 4.4.6 bug in the earlyer versions.

If you only use this in the array PHP doesn't segfault. You need to
have the full array.
to segfault PCRE 7.0 and make a stack overflow.

/* 11 */ "/(<br[[:space:]]*\/?".">){2,}/S",
/* 12 */ "/([\n]*(<br[[:space:]]*\/?".">)*)*/S",

This is a code who crash php 4.4.6 in both binary or libphp/apache version.

<?php

$letexte=" ";

$cherche1 = array(
 /* 0 */ /* 1 */ /* 2 */ /* 3 */ /* 4 */ /* 5 */ /* 6 */ /* 7 */ /* 8 */ /* 9 */ /* 10 */ /* 11 */ /* 12 */ /* 13 */ /* 14 */ );
 $remplace1 = array(
 /* 0 */ /* 1 */ /* 2 */ /* 3 */ /* 4 */ /* 5 */ /* 6 */ /* 7 */ /* 8 */ /* 9 */ /* 10 */ /* 11 */ /* 12 */ /* 13 */ /* 14 */ );
 $letexte = preg_replace($cherche1, $letexte = preg_replace("@^ "/\n(----+|____+)/S",
"/\n-- */S",
"/\n- */S",
"/\n_ +/S",
"/(^|[^{])[{][{][{]/S",
"/[}][}][}]($|[^}])/S",
"/(( *)\n){2,}(<br[[:space:]]*\/?".">)?/S",
"/[{][{]/S",
"/[}][}]/S",
"/[{]/S",
"/[}]/S",
"/(<br[[:space:]]*\/?".">){2,}/S",
"/([\n]*(<br[[:space:]]*\/?".">)*)*/S",
"/<quote>/S",
"/<\/quote>/S"
"\n\n$ligne_horizontale\n\n",
"\n — ",
"\n $puce ",
"\n ",
"\$1\n\n$debut_intertitre",
"$fin_intertitre\n\n\$1",
"",
"",
"",
"",
"",
"",
"",
"<blockquote class=\"spip\">",
"</blockquote>"
$remplace1, $letexte);
 @S", "", $letexte);

print $letexte;

?>

So now I need to recompile one more time PHP with debug in order to give
you more infos.

gdb /opt/php/bin/php
(gdb) set args bug_pcre.php
(gdb) run
Starting program: /opt/php/bin/php bug_pcre.php

I am not alone to have this issue so why to not get back to PCRE 6.6
until PCRE
team has identified this bug ?

Hi Nuno,

I can reproduce this bug with this code
please confirm if you can also on your version
of PHP 4.4.6.

Ok even this bug isn't in PHP and you know
there is an overflow inside last version PCRE 7.0
Why to you still use 7.0 in the official "stable"
release of PHP 4.4.6 and not downgrade to 6.6 ?

I can reproduce this bug with this code
please confirm if you can also on your version
of PHP 4.4.6.

Ok even this bug isn't in PHP and you know
there is an overflow inside last version PCRE 7.0
Why to you still use 7.0 in the official "stable"
release of PHP 4.4.6 and not downgrade to 6.6 ?

Hi,

I've tried the regexes you mention, but I couldn't reproduce any
crash. We need a short reproducing script (e.g. the regex + sample
data that makes it crash). Anyway this isn't a bug (if any) in PHP,
but rather in PCRE, so you should get that short reproducing script
and contact the PCRE authors (pcre-dev@exim.org). I'm also on that ML.

Regards,
Nuno

Subject: PHP 4.4.6 Segfault with PCRE 7.0 not with 6.6

EN

After upgrading PHP from 4.4.4 to 4.4.6 our customers using
SPIP, Joomla Mambot, etc. their websites display a blank page
or 500 due to a segfault of PHP.

I have backported PCRE from version 7.0 to 6.6 on PHP 4.4.6.
No more segfault of PHP and SPIP works as before.
