Linux-Mandrake Security Update Advisory
________________________________________________________________________
Package name: mod_php3
Date: September 13th, 2000
Advisory ID: MDKSA-2000:048
Affected versions: 6.1, 7.0, 7.1
________________________________________________________________________
Problem Description:
A problem exists with PHP3 and PHP4 scripts regarding RFC 1867-based
file uploads. PHP saves uploaded files in a temporary directory on the
server, using a temporary name that is referenced as the variable $FOO
where "FOO" is the name of the file input tag in the submitted form.
Many PHP scripts process $FOO without taking measures to ensure that it
is in fact a file that resides in the temporary directory. Because of
this, it is possible for a remote attacker to supply an arbitrary file
name as the value for $FOO by submitting a standard form input tag by
that name, and thus cause the PHP script to process arbitrary files.
The vulnerability exists in various scripts, and not necessarily with
PHP itself, as the script determines what actions to perform on the
uploaded file. The new versions of both PHP3 and PHP4 make it easier
to secure scripts from this particular vulnerability. They include a
new function that makes it easy to determine whether a certain
filename is a temporary uploaded file or not:
/* Text whether a file is an uploaded file or not */
is_uploaded_file($path);
While there is no security vulnerability with PHP3 and PHP4, this
upgrade is offered as a convenience because it includes the above
illustrated method of file testing.

Please verify these md5 checksums of the updates prior to upgrading to
ensure the integrity of the downloaded package. You can do this by
running the md5sum program on the downloaded package by using
"md5sum package.rpm".

To upgrade automatically, use « MandrakeUpdate ».
If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and uprade with "rpm -Uvh package_name".
You can download the updates directly from:
ftp://ftp.linux.tucows.com/pub/distributions/Mandrake/Mandrake/updates
ftp://ftp.free.fr/pub/Distributions_Linux/Mandrake/updates
Or try one of the other mirrors listed at:
http://www.linux-mandrake.com/en/ftp.php3.
Updated packages are available in the "updates/[ver]/RPMS/" directory.
For example, if you are looking for an updated RPM package for
Linux-Mandrake 7.1, look for it in "updates/7.1/RPMS/". Updated source
RPMs are available as well, but you generally do not need to download
them.
Please be aware that sometimes it takes the mirrors a few hours to
update, so if you want an immediate upgrade, please use one of the two
above-listed mirrors.
