Overview

There is a remotely exploitable buffer overflow in the Squid proxy/cache server. Exploitation of this vulnerability could lead to an intruder gaining a shell on the target Squid server.

Description

Squid versions 2.3 and 2.4 are vulnerable to a buffer overflow in the code that parses FTP requests. A crafted FTP request can cause a Squid child process to dump core, and multiple requests can cause a denial of service. It is also reported that this vulnerability may be exploitable to allow arbitrary execution of code. This is not yet confirmed, and does not seem to be a trivial task. In order to exploit this vulnerability, the attacker must be a local user, or the server must permit anonymous logins.

---

Impact

Exploitation of this vulnerability results in a denial of service. It could also permit an intruder to execute arbitrary code on the target Squid server with the privileges of the Squid process, usually super-user/root. Note that exploiting this vulnerability to execute arbitrary code is not yet confirmed.

---

Solution

Upgrade to Squid-2.4.STABLE4 or apply the patches provided by your vendor.

---

Configure the Squid server to drop super-user/root privilege by specifying the chroot option used in squid.conf. If this is done, the attacker will only be able to execute arbitrary code as the user specified in the configuration file.

HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #028
Originally issued: 01 March '02
---------------------------------------------------------------

The information in the following Security Bulletin should be acted
upon as soon as possible. Hewlett-Packard Company will not be
liable for any consequences to any customer resulting from the
customer’s failure to fully implement instructions in this Security
Bulletin as soon as possible.

Because the vulnerability does not require a HP Secure OS
1.0 patch or re-packaging of the RPM affected by the bulletin, the
RPMs have not been produced or tested by Hewlett-Packard Company.

---------------------------------------------------------------
PROBLEM: Security vulnerability in PHP

PLATFORM: Any system running HP Secure OS software for Linux Release 1.0

DAMAGE: Remote attacker could potentially execute arbitrary code

SOLUTION: Apply the appropriate RPMs (see section B below)

MANUAL ACTIONS: None

AVAILABILITY: The RPMs are available now.
---------------------------------------------------------------
A. Background

PHP is an HTML-embeddable scripting language. A number of flaws have
been found in the way PHP handles multipart/form-data POST requests.
Each of these flaws could allow an attacker to execute arbitrary code
on the remote system. The php package is not included in the default
installation of HP Secure OS Software for Linux release 1.0.

B. Fixing the problem

Hewlett-Packard Company recommends that customers download the RPMs
listed in the following Red Hat Security Advisory:

2002-02-27 php-manual (RHSA-2002-035) Updated PHP packages
are available

<http://www.redhat.com/support/errata/RHSA-2002-035.html&gt;

To install the security bulletin RPMs, use the following sequence
of commands:

1. If you use the tripwire product, we recommend that you run a
a consistency check and fix any violations before installing
the security bulletin RPM.

tripwire --check --interactive

2. Install the bulletin RPM from the root account.

rpm -F <package name>

3. Update the tripwire database

tripwire --check --interactive

NOTE:
The rpm -q command can be used to determine if the
product is installed. Hewlett-Packard Company recommends applying the
Security Bulletin fixes to installed packages only. The -F option
to the RPM installer will only apply the fix if the package is
currently installed on the system. Dependent RPMs can be found by
using the “Find Latest RPMs” search facility at
<http://www.redhat.com/apps/download&gt;. To find the latest dependent

SuSE Security Announcement

Package: squid
Announcement-ID: SuSE-SA:2002:008
Date: Mon Mar 5 13:00:00 CET 2002
Affected SuSE products: 6.4, 7.0, 7.1, 7.2, 7.3,
Enterprise Server 7
Vulnerability Type: remote command execution
Severity (1-10): 6
SuSE default package: no
Other affected systems: all systems running vulnerable squid

Content of this advisory:

1. security vulnerability resolved: Heap overflow in squid.
   problem description, discussion, solution and upgrade information
2. pending vulnerabilities, solutions, workarounds
3. standard appendix (further information)

---

1. problem description, brief discussion, solution, upgrade information

The widely used proxy-server squid contains a heap overflow in one of its
URL constructing functions. Incorrect length-calculations for the user and
passwd fields in ftp-URLs turned out to be the origin of the problem. Only
users from hosts listed in squids ACL-files could trigger the overflow.
The ftp-URL problem is not present in the 6.4, 7.0 and 7.1 distributions,
but other security releated bugs have been fixed there.
A complete history can be found at

<http://www.squid-cache.org/Versions/v2/2.4/bugs/&gt;

Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command “rpm -Fhv file.rpm” to apply
the update. For users of our SLES-based products, please use the yast
online update.

For the updates to take effect, invoke the following command as root:

/etc/rc.d/squid restart

If you added the htcp_port directive to your squid configuration file
you might now see a warning in the logs about that directive being
unrecognized. While this does not prevent squid from starting, you can
safely remove the directive from squid.conf since HTCP support is
disabled now.

Please note that there are two binary and two source packages for almost
every distribution available.

2. Pending vulnerabilities in SuSE Distributions and Workarounds:

- ucd-snmpd
The UCD snmpd contains various security releated bugs.
We are currently reviewing the code and available fixes to ensure
they all get fixed. Patches will be available as soon as possible.
It is strongly recommended to filter SNMP (TCP and UDP packets
with destination of port 161) traffic.

- hanterm/wmtv
The recently reported vulnerabilities in hanterm and wmtv do not
affect SuSE installations because they are not installed setuid
or setgid.

- cipe
We are about to prepare kernel update packages that fix a DoS
problem in the kernel modules for the cipe encrypted tunneling software.

3. standard appendix: authenticity verification, additional information

- Package authenticity verification:

SuSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:

1. md5sums as provided in the (cryptographically signed) announcement.

2. using the internal gpg signatures of the rpm package.

3. execute the command
   md5sum <name-of-the-file.rpm>
   after you downloaded the file from a SuSE ftp server or its mirrors.
   Then, compare the resulting md5sum with the one that is listed in the
   announcement. Since the announcement containing the checksums is
   cryptographically signed (usually using the key [email protected]),
   the checksums show proof of the authenticity of the package.
   We disrecommend to subscribe to security lists which cause the
   email message containing the announcement to be modified so that
   the signature does not match after transport through the mailing
   list software.
   Downsides: You must be able to verify the authenticity of the
   announcement in the first place. If RPM packages are being rebuilt
   and a new version of a package is published on the ftp server, all
   md5 sums for the files are useless.

4. rpm package signatures provide an easy way to verify the authenticity
   of an rpm package. Use the command
   rpm -v --checksig <file.rpm>
   to verify the signature of the package, where <file.rpm> is the
   filename of the rpm package that you have downloaded. Of course,
   package authenticity verification can only target an uninstalled rpm
   package file.
   Prerequisites:
   a) gpg is installed
   b) The package is signed using a certain key. The public part of this
   key must be installed by the gpg program in the directory
   ~/.gnupg/ under the user’s home directory who performs the
   signature verification (usually root). You can import the key
   that is used by SuSE in rpm packages for SuSE Linux by saving
   this announcement to a file (“announcement.txt”) and
   running the command (do “su -” to be root):
   gpg --batch; gpg < announcement.txt | gpg --import
   SuSE Linux distributions version 7.1 and thereafter install the
   key “[email protected]” upon installation or upgrade, provided that
   the package gpg is installed. The file containing the public key
   is placed at the toplevel directory of the first CD (pubring.gpg)
   and at <ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de&gt; .
