Cisco Security Advisory: Cisco IOS Software H.323 Denial of Service
Vulnerabilities
Advisory ID: cisco-sa-20100324-h323
Revision 1.0
For Public Release 2010 March 24 1600 UTC (GMT)
+---------------------------------------------------------------------
Summary
=======
The H.323 implementation in Cisco IOS Software contains two
vulnerabilities that may be exploited remotely to cause a denial of
service (DoS) condition on a device that is running a vulnerable
version of Cisco IOS Software.
Cisco has released free software updates that address these
vulnerabilities. There are no workarounds to mitigate these
vulnerabilities other than disabling H.323 on the vulnerable device
if H.323 is not required.
This advisory is posted at:
http://www.cisco.com/warp/public/707/cisco-sa-20100324-h323.shtml
Note: The March 24, 2010, Cisco IOS Software Security Advisory
bundled publication includes seven Security Advisories. All the
advisories address vulnerabilities in Cisco IOS Software. Each
advisory lists the releases that correct the vulnerability or
vulnerabilities detailed in the advisory. The table at the following
URL lists releases that correct all Cisco IOS Software
vulnerabilities that have been published on March 24, 2010, or
earlier:

Affected Products
=================
This vulnerability only affects devices running Cisco IOS Software
with H.323 voice services enabled.
Vulnerable Products
+------------------
Cisco devices that are running affected Cisco IOS Software versions
that are configured to process H.323 messages are affected by these
vulnerabilities. H.323 is not enabled by default.
To determine if the Cisco IOS Software device is running H.323
services, use the "show process cpu | include 323" command, as shown in
the following example:
Router#show process cpu | include 323
249 16000 3 5333 0.00% 0.00% 0.00% 0 CCH323_CT
250 0 1 0 0.00% 0.00% 0.00% 0 CCH323_DNS
Router#
In the previous example the processes CCH323_CT and CCH323_DNS are
running on the device; subsequently, the device is listening to H.323
messages. The device is vulnerable as long as any of these processes
(or similar) are active.
Note: Only H.323 listening on port TCP 1720 is affected.
To determine the Cisco IOS Software release that is running on a
Cisco product, administrators can log in to the device and issue the
"show version" command to display the system banner. The system banner
confirms that the device is running Cisco IOS Software by displaying
text similar to "Cisco Internetwork Operating System Software" or
"Cisco IOS Software." The image name displays in parentheses,
followed by "Version" and the Cisco IOS Software release name. Other
Cisco devices do not have the show version command or may provide
different output.
The following example identifies a Cisco product that is running
Cisco IOS Software Release 12.3(26) with an installed image name of
C2500-IS-L:
Router#show version
Cisco Internetwork Operating System Software
IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2)

Cisco IOS Software Release 12.4(20)T with an installed image name of
C1841-ADVENTERPRISEK9-M:
Router#show version

Products Confirmed Not Vulnerable
+--------------------------------
Cisco IOS XR Software is not affected by these vulnerabilities.
No other Cisco products are currently known to be affected by these
vulnerabilities.
Details
=======
H.323 is the ITU standard for real-time multimedia communications and
conferencing over packet-based (IP) networks. A subset of the H.323
standard is H.225.0, a standard used for call signaling protocols and
media stream packetization over IP networks.
The H.323 implementation in Cisco IOS Software contains two DoS
vulnerabilities. An attacker can exploit these vulnerabilities
remotely by sending crafted H.323 packets to the affected device that
is running Cisco IOS Software. A TCP three-way handshake is needed to
exploit these vulnerabilities.
When exploited, the first vulnerability may lead to an interface
queue wedge. The second vulnerability may cause a memory leak and, in
most cases, the device to reload.
An interface queue wedge is a class of vulnerability in which certain
packets are received and queued by a Cisco IOS router or switch, but
due to a processing error, are never removed from the queue.
Received packets are counted against the interface input "queue,"
which is of a limited and relatively small size. For example, on most
interface types on most platforms the default interface input queue
is 75 packets, a value that can be configured via the hold-queue
value in interface configuration command. Once the input queue
contains nothing but packets that, due to a bug, will never be
dequeued, the queue is said to be wedged. More recently this
condition has been termed a "blocked interface".
This can be seen on a Cisco IOS device when the input queue size is
equal to or greater than (depending on the Cisco IOS Software
Release) the input queue max value, as shown below. In this example,
the current "size" of the input queue is 75, which is equal to the
"max" size of the input queue, which is also 75.

mechanisms that may be used to identify a blocked interface on Cisco
IOS Software (including an EEM script specifically for this purpose
and a whitepaper describing how this condition can be detected using
SNMP) go to:
http://blogs.cisco.com/security/comments/cisco_ios_queue_wedges_explained
To display detected memory leaks, use the "show memory debug leaks"
command in privileged EXEC mode.
Router#show memory debug leaks

Processor memory
Address Size Alloc_pc PID Alloc-Proc Name

65961B38 1940 622265A4 196 CCH323_CT CCH323_CT
The previous example shows a memory leak in the process CCH323_CT.
The show memory debug leaks command was introduced in Cisco IOS
Software versions 12.3(8)T1 and 12.2(25)S, respectively.
These vulnerabilities are documented in Cisco Bug IDs CSCta19962 and
CSCtb93855 and have been assigned CVE IDs CVE-2010-0582 and
CVE-2010-0583.
Vulnerability Scoring Details
=============================
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Security Advisory is done in accordance with CVSS
version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then
compute environmental scores to assist in determining the impact of
the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding
CVSS at:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to help compute the

advisory may cause the affected device to experience an interface
queue wedge or to reload. Theses vulnerabilities could be exploited
repeatedly to cause an extended DoS condition.
Software Versions and Fixes
===========================
When considering software upgrades, also consult
http://www.cisco.com/go/psirt and any subsequent advisories to
determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current
hardware and software configurations will continue to be supported
properly by the new release. If the information is not clear, contact
the Cisco Technical Assistance Center (TAC) or your contracted
maintenance provider for assistance.
Each row of the Cisco IOS software table (below) names a Cisco IOS
release train. If a given release train is vulnerable, then the
earliest possible releases that contain the fix (along with the
anticipated date of availability for each, if applicable) are listed
in the "First Fixed Release" column of the table. The "Bundle First
Fixed Release" column indicates the earliest possible releases which
have fixes for all the published vulnerabilities in this Cisco IOS
Security Advisory bundled publication. Cisco recommends upgrading to
the latest available release where possible.

Workarounds
===========
There are no workarounds to mitigate these vulnerabilities apart from
disabling H.323 if the Cisco IOS device does not need it. Applying
access lists on interfaces that should not accept H.323 traffic and
putting firewalls in strategic locations may greatly reduce exposure
until an upgrade can be performed.
Cisco provides Solution Reference Network Design (SRND) guides to
help design and deploy networking solutions, which can be found at
http://www.cisco.com/go/srnd Voice Security best practices are
covered in the Cisco Unified Communications SRND Based on Cisco
Unified Communications Manager 6.x at:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/6x/security.html
You can use the "call service stop forced" command under the "voice
service voip" mode, as shown in the following example:
voice service voip
h323
call service stop forced
Note: The "call service stop forced" command disables all H.323 call
processing.
Additional mitigations that can be deployed on Cisco devices within
the network are available in the companion document "Cisco Applied
Mitigation Bulletin: Identifying and Mitigating Exploitation of the
Denial of Service Vulnerabilities in Cisco Unified Communications
Manager and Cisco IOS Software", which is available at the following
location:
http://www.cisco.com/warp/public/707/cisco-amb-20100324-voice.shtml
Obtaining Fixed Software
========================
Cisco has released free software updates that address these
vulnerabilities. Prior to deploying software, customers should
consult their maintenance provider or check the software for feature
set compatibility and known issues specific to their environment.
Customers may only install and expect support for the feature sets
they have purchased. By installing, downloading, accessing or
otherwise using such software upgrades, customers agree to be bound
by the terms of Cisco's software license terms found at:
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html
or as otherwise set forth at Cisco.com Downloads at:
http://www.cisco.com/public/sw-center/sw-usingswc.shtml
Do not contact psirt@...co.com or security-alert@...co.com for
software upgrades.
Customers with Service Contracts
+-------------------------------
Customers with contracts should obtain upgraded software through
their regular update channels. For most customers, this means that
upgrades should be obtained through the Software Center on Cisco's
worldwide website at http://www.cisco.com.
Customers using Third Party Support Organizations
+------------------------------------------------
Customers whose Cisco products are provided or maintained through
prior or existing agreements with third-party support organizations,
such as Cisco Partners, authorized resellers, or service providers
should contact that support organization for guidance and assistance
with the appropriate course of action in regards to this advisory.
The effectiveness of any workaround or fix is dependent on specific
customer situations, such as product mix, network topology, traffic
behavior, and organizational mission. Due to the variety of affected
products and releases, customers should consult with their service
provider or support organization to ensure any applied workaround or
fix is the most appropriate for use in the intended network before it
is deployed.
Customers without Service Contracts
+----------------------------------
Customers who purchase direct from Cisco but do not hold a Cisco
service contract, and customers who purchase through third-party
vendors but are unsuccessful in obtaining fixed software through
their point of sale should acquire upgrades by contacting the Cisco
Technical Assistance Center (TAC). TAC contacts are as follows.
* +1 800 553 2447 (toll free from within North America)
* +1 408 526 7209 (toll call from anywhere in the world)
* e-mail: tac@...co.com
Customers should have their product serial number available and be
prepared to give the URL of this notice as evidence of entitlement to
a free upgrade. Free upgrades for non-contract customers must be
requested through the TAC.
Refer to:
http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html
for additional TAC contact information, including localized telephone
numbers, and instructions and e-mail addresses for use in various
languages.
