Bug description: LDAP in nsswitch.conf causes segfault when resolving
hostnames in PHP
Description:
------------
Any hostname resolve in PHP causes a segmentation fault.
It only happens when this file contains the ldap keyword.
When removed, everything works fine.
Everything works great when using modphp. It only happens when using the
executable.
[EMAIL PROTECTED]: / # cat /etc/nsswitch.conf
group: files ldap
group_compat: nis
hosts: files dns
networks: files
passwd: files
passwd_compat: nis
shells: files
We've seen it on two seperate systems.
It's on PHP versions 5.0.5, 5.1.1 and 5.1.2
Server #1:
openldap 2.2.30
nss_ldap 1.244
php 5.0.5
FreeBSD 5.4-RELEASE-p8
Server #2:
nss_ldap-1.239
openldap-client-2.2.27
php 5.1.2
FreeBSD 5.4-RELEASE-p8
Reproduce code:
---------------
[EMAIL PROTECTED]: / # echo "<? echo gethostbyname('php.net'); ?>" | php
[EMAIL PROTECTED]: / # echo "<? mysql_connect( 'badgerbadger', '', '' ); ?>" |
php
#!/usr/local/bin/php
<?php
// this
echo gethostbyname( 'php.net' );
// AND this too
mysql_connect( 'blahdieblah', '', '' );
// and anything that resolves.
?>
Expected result:
----------------
An IP-address and an error because the mysql host doesn't exist.
Actual result:
--------------
Segmentation fault on any line that resolves a hostname.
