Summary: Chroot patch
Product: Apache httpd-2
Version: 2.2.6
Platform: Other
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P2
Component: Core
AssignedTo: bugs@httpd.apache.org
ReportedBy: mitko@banksoft-bg.com
This patch adds new configuration directive named "ChrootDir".
For example: ChrootDir /var/www-chroot
Chroot is called before changing to the non-privileged user.
. . .
if( NULL != unixd_config.chroot_dir ) {
if(geteuid()) {
ap_log_error(APLOG_MARK, APLOG_ALERT,errno,NULL,
"Cannot chroot when not started as root");
return -1;
}
if( chdir( unixd_config.chroot_dir ) != 0 ) {
ap_log_error(APLOG_MARK, APLOG_ALERT, errno,NULL,
"Can't chdir to %s", unixd_config.chroot_dir);
return -1;
}
if( chroot( unixd_config.chroot_dir ) != 0 ) {
ap_log_error(APLOG_MARK, APLOG_ALERT, errno,NULL,
"Can't chroot to %s", unixd_config.chroot_dir);
return -1;
}
if( chdir( "/" ) != 0 ) {
ap_log_error(APLOG_MARK, APLOG_ALERT, errno,NULL,
"Can't chdir to new root");
return -1;
}
}
. . .
setuid(unixd_config.user_id) == -1))
. . .
I use this patch from version 2.0.50 to 2.2.6 and have no problems.

Keep in mind http://it.slashdot.org/article.pl?sid=07/09/27/2256235
If you are submitting this as a security necessity, you are already off base.
Not disputing that chroot is not useful, but it should not be viewed as any
security 'feature'.

I wrote a similar patch but it has not been accepted (yet). Maybe people are
not that concerced about security as I am. I hope the best for your patch.
