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 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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100324-h323. 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: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100324-bundle Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar10.html

This vulnerability only affects devices running Cisco IOS Software with H.323 voice services enabled.
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:

Cisco IOS XR Software is not affected by these vulnerabilities.
No other Cisco products are currently known to be affected by these vulnerabilities.
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.

For more information about queue wedges and a few detection 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
Adding blocks for GD...
I/O memory
Address Size Alloc_pc PID Alloc-Proc Name
Processor memory
Address Size Alloc_pc PID Alloc-Proc Name
640854D4 1940 622265A4 196 CCH323_CT CCH323_CT
640EA5E8 1940 622265A4 196 CCH323_CT CCH323_CT
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.
Caution: All show memory debug commands must be used on
customer networks only to diagnose the router for memory leaks when memory
depletion is observed. These commands may cause high CPU utilization and may
cause time sensitive protocols to flap. These commands are recommended to be
used in maintenance windows when the device is not in a scaled
condition.
These vulnerabilities are documented in Cisco Bug IDs CSCta19962 ( registered customers only) and CSCtb93855 ( registered customers only) and have been assigned CVE IDs CVE-2010-0582 and CVE-2010-0583.
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 h423 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://tools.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20100324-voice
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.
