Brief items
May 23, 2007
This article was contributed by Jake Edge.
Broadband routers are ubiquitous these days, so much so that they go
unnoticed; unless they fail, no one pays any attention to them. These
routers run some kind of embedded OS, often Linux, on a fairly capable
hardware platform which makes them interesting targets for an attacker.
Because they tend to be invisible and unmonitored, subverting routers without
affecting their normal function makes a perfect hidden space for malicious
code to run.
As a recent Bugtraq posting
from Gadi Evron points out, there have already been a few reports of
vulnerable routers and we can only expect to see more. Even if the
router manufacturers are staying on top of vulnerabilities in their
codebase, which is not a foregone conclusion, there are still serious
questions about how a largely non-technical user base will be
assisted or forced into upgrading their firmware. The logistics of
getting the right firmware and upgrade program into a user's hands and having
them run it correctly so that their router does not turn into a brick is
rather daunting. One can only imagine the volume of support calls that
could be generated.
In many cases, the router makers are selling special versions of their
hardware to specific broadband providers who sell or lease them to their
customers. This allows the router maker to leave the support burden
to the providers who typically already have a large technical support
organization. It is unclear whose responsibility it is to track security
issues and ensure that any critical vulnerabilities are patched, it probably
depends on the contract. The broadband providers typically host any updates
and manufacturer's websites refer users looking for updates there. It
certainly seems like a situation where vulnerabilities could fall through
the cracks.
As an example, Qwest provides a router for their DSL customers, made by
Actiontec, that is based on Linux 2.4.17 which was
released in December 2001.
Since that time, there have been numerous 2.4 kernel releases, with
the most recent, 2.4.34.4 having been
released in April. Many
of those releases have been done for security problems in various subsystems,
including one for
CAN-2005-0449
which could potentially lead to a denial of service from a bug in the
netfilter packet filtering code. It is unclear if the router is susceptible
to this particular problem, one hopes not, but there are plenty of other
candidates, in the other security bug fixes or any that come up
in the future.
Any outward (broadband) facing network service is, of course, a potential
vector for security issues. Many of these routers serve web pages for
configuration as well as allowing telnet or ssh
connections for maintenance. One hopes that these services can only be
configured to
run on the internal network. Even then, many of these routers provide
a wireless bridge in addition to ethernet on the LAN side and that may
expose those services more broadly.
Once a router has been subverted, it could be turned to any number of
malicious tasks; the simplest might be to add it to a botnet for spamming
or distributed denial of service. It does not take much in the way of
CPU horsepower or RAM to perform those kinds of tasks and they could easily
run on many routers without interfering in any noticeable way. An attack
focused on a particular individual could potentially intercept and report
on all of their internet traffic; there is no better place for spyware
on a network.
It is not only routers, of course, that are vulnerable, any embedded
device could be a target, but routers have the network connectivity
that makes them particularly interesting and accessible. Long before
we start putting wireless network connected Linux systems in
control of our cars,
the need for vigilance about security updates for embedded devices must
be ingrained into users. It needs to become as obvious to people as
the need for an anti-virus scanner on Windows has become.

| Description: |
The atalk_sum_skb function in AppleTalk for Linux kernel 2.6.x before
2.6.21, and possibly 2.4.x, allows remote attackers to cause a denial of
service (crash) via an AppleTalk frame that is shorter than the specified

CVE #(s): | CVE-2007-1864
CVE-2007-2509
CVE-2007-2510
|
| Created: | May 8, 2007 |
Updated: | July 18, 2007 |
| Description: |
A heap buffer overflow flaw was found in the PHP 'xmlrpc' extension. A
PHP script which implements an XML-RPC server using this extension
could allow a remote attacker to execute arbitrary code as the 'apache'
user. Note that this flaw does not affect PHP applications using the
pure-PHP XML_RPC class provided in /usr/share/pear. (CVE-2007-1864)
A flaw was found in the PHP 'ftp' extension. If a PHP script used this
extension to provide access to a private FTP server, and passed untrusted
script input directly to any function provided by this extension, a remote
attacker would be able to send arbitrary FTP commands to the server.
(CVE-2007-2509)
A buffer overflow flaw was found in the PHP 'soap' extension, regarding the
handling of an HTTP redirect response when using the SOAP client provided
by this extension with an untrusted SOAP server. No mechanism to trigger
this flaw remotely is known. (CVE-2007-2510) |

postgresql: SQL injection
| Package(s): | postgresql |
CVE #(s): | CVE-2006-2313
CVE-2006-2314
|
| Created: | May 24, 2006 |
Updated: | June 6, 2007 |
| Description: |
The PostgreSQL team has put out a set of "urgent updates" (in the form of the 7.3.15, 7.4.13, 8.0.8, and 8.1.4 releases) closing a
newly-discovered set of SQL injection issues. Details about the problem
can be found on the
technical information page; in short: multi-byte encodings can be used
to defeat normal string sanitizing techniques. The update fixes one problem
related to invalid multi-byte characters, but punts on another by simply
disallowing the old, unsafe technique of escaping single quotes with a
backslash. |

| Description: |
Several flaws were found in the way SeaMonkey processed certain malformed
JavaScript code. A malicious web page could execute JavaScript code in such
a way that may result in SeaMonkey crashing or executing arbitrary code as
the user running SeaMonkey. (CVE-2007-0775, CVE-2007-0777)
Several cross-site scripting (XSS) flaws were found in the way SeaMonkey
processed certain malformed web pages. A malicious web page could display
misleading information which may result in a user unknowingly divulging
sensitive information such as a password. (CVE-2006-6077, CVE-2007-0995,
CVE-2007-0996)
A flaw was found in the way SeaMonkey cached web pages on the local disk. A
malicious web page may be able to inject arbitrary HTML into a browsing
session if the user reloads a targeted site. (CVE-2007-0778)
A flaw was found in the way SeaMonkey displayed certain web content. A
malicious web page could generate content which could overlay user
interface elements such as the hostname and security indicators, tricking a
user into thinking they are visiting a different site. (CVE-2007-0779)
Two flaws were found in the way SeaMonkey displayed blocked popup windows.
If a user can be convinced to open a blocked popup, it is possible to read
arbitrary local files, or conduct an XSS attack against the user.
(CVE-2007-0780, CVE-2007-0800)
Two buffer overflow flaws were found in the Network Security Services (NSS)
code for processing the SSLv2 protocol. Connecting to a malicious secure
web server could cause the execution of arbitrary code as the user running
SeaMonkey. (CVE-2007-0008, CVE-2007-0009)
A flaw was found in the way SeaMonkey handled the "location.hostname" value
during certain browser domain checks. This flaw could allow a malicious web
site to set domain cookies for an arbitrary site, or possibly perform an
XSS attack. (CVE-2007-0981) |
