Note
New and Changed Information
The following sections list the new information about the Cisco 3200 Series Mobile Access Routers for Cisco IOS Release 12.3(8)YD. This information also applies to Cisco IOS Release 12.3(8)YD1.
New Software Features in Release 12.3(8)YD
The following sections describe the new software features supported by the Cisco 3200 Series Mobile Access Routers for Release 12.3(8)YD.
Foreign Agent Route Optimization
The Mobile IP Protocol version 4 does not allow direct routing from one mobile node to another mobile node or to a mobile network behind a mobile router. The protocol requires the traffic to go through the home agent (HA), creating the problem of triangular routing.
The Foreign Agent (FA) Route Optimization feature injects mobile network routes into a foreign agent routing table, enabling routing directly from one mobile network to another mobile network. The resulting route optimization improves deployments that are running latency-sensitive applications.
Declassification or Zeroization
Declassification, sometimes referred to as zeroization, erases all potentially sensitive information in the router memory. This includes the erasure of the main memory, cache memories and other memories containing packet data, NVRAM, and selected files in Flash, such as crash dumps. Declassification is launched by taking an action. The action is determined by the configuration of the router.
New Software Features in Release 12.3(8)T
For information regarding the features supported in Cisco IOS Release 12.3(8)T, see the Cross-Platform Release Notes and New Feature Documentation links at the following location on Cisco.com:

Important Notes
The following sections contain important notes concerning the new software features supported by the Cisco 3200 Series Mobile Access Router for Release 12.3(8)YD. These notes also apply to Cisco IOS Release 12.3(8)YD1.
Foreign Agent Route Optimization
When the Foreign Agent Route Optimization feature is configured on a Cisco 3200 router, the home agent must be running Cisco IOS Software Release 12.3(11)T or later. Older releases may result in double encapsulation failures.
Caveats
Caveats describe unexpected behavior or defects in the Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.
Caveats in Cisco IOS Release 12.3(8)T are also in Release 12.3(8)YD. For information on caveats in Cisco IOS Release 12.3(8)T, see the Caveats for Cisco IOS Release 12.3(8)T document. This document lists severity 1 and 2 caveats; the documents is located on Cisco.com.
Note
Resolved Caveats - Release 12.3(8)YD1
This section documents possible unexpected behavior by Cisco IOS Release 12.3(8)YD1 and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
Cisco IOS may permit arbitrary code execution after exploitation of a heap-based buffer overflow vulnerability. Cisco has included additional integrity checks in its software, as further described below, that are intended to reduce the likelihood of arbitrary code execution.
Cisco has made free software available that includes the additional integrity checks for affected customers.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20051102-timers.shtml.
•
A document that describes how the Internet Control Message Protocol (ICMP) could be used to perform a number of Denial of Service (DoS) attacks against the Transmission Control Protocol (TCP) has been made publicly available. This document has been published through the Internet Engineering Task Force (IETF) Internet Draft process, and is entitled "ICMP Attacks Against TCP" (draft-gont-tcpm-icmp-attacks-03.txt).
These attacks, which only affect sessions terminating or originating on a device itself, can be of three types:
1. Attacks that use ICMP "hard" error messages
2. Attacks that use ICMP "fragmentation needed and Don't Fragment (DF) bit set" messages, also known as Path Maximum Transmission Unit Discovery (PMTUD) attacks
3. Attacks that use ICMP "source quench" messagesSuccessful attacks may cause connection resets or reduction of throughput in existing connections, depending on the attack type.
Multiple Cisco products are affected by the attacks described in this Internet draft.
Cisco has made free software available to address these vulnerabilities. In some cases there are workarounds available to mitigate the effects of the vulnerability.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20050412-icmp.shtml.
The disclosure of these vulnerabilities is being coordinated by the National Infrastructure Security Coordination Centre (NISCC), based in the United Kingdom. NISCC is working with multiple vendors whose products are potentially affected. Its posting can be found at: http://www.niscc.gov.uk/niscc/docs/re-20050412-00303.pdf?lang=en.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
