Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images, depending on the platform. Each feature set contains a specific set of Cisco IOS features. Release 12.4(11)XV supports the same feature sets as Releases 12.4 and 12.4(11)T, but Release 12.4(11)XV includes new features supported by the Cisco 2800 series routers.
Caution The Cisco IOS images with strong encryption (including, but not limited to, 168-bit [3DES] data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States probably require an export license. Customer orders can be denied or subject to delay as a result of United States government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.
Table 2 lists the feature and feature sets supported in Cisco IOS Release 12.4(11)XV.
The tables use the following conventions:
•In—The number in the `In' column indicates the Cisco IOS release in which the feature was introduced. For example, "12.4(11)XV" indicates that the feature was introduced in 12.4(11)XV. If a cell in this column is empty, the feature was included in a previous release or in the initial base release.
•Yes—The feature is supported in the software image.
•No—The feature is not supported in the software image.
Note These feature set tables contain only a selected list of features, which are cumulative for Release 12.4(11)nn early deployment releases only (nn identifies each early deployment release). The tables do not list all features in each image—additional features are listed in Cross-Platform Release Notes for Cisco IOS Release 12.4(11)T and Release 12.4(11)T Cisco IOS documentation.

CSCse56501A device running Cisco IOS software that has Internet Protocol version 6 (IPv6) enabled may be subject to a denial of service (DoS) attack. For the device to be affected by this vulnerability the device also has to have certain Internet Protocol version 4 (IPv4) User Datagram Protocol (UDP) services enabled. To exploit this vulnerability an offending IPv6 packet must be targeted to the device. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation will prevent the interface from receiving any additional traffic. The only exception is Resource Reservation Protocol (RSVP) service, which if exploited, will cause the device to crash. Only the interface on which the vulnerability was exploited will be affected.
Cisco is providing fixed software to address this issue. 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-20080326-IPv4IPv6.shtml.

CSCsh58082 SIP: A router may reload due to SIP trafficCisco devices running an affected version of Internetwork Operating System (IOS) which supports Session Initiation Protocol (SIP) are affected by a vulnerability that may lead to a reload of the device when receiving a specific series of packets destined to port 5060. This issue is compounded by a related bug which allows traffic to TCP 5060 and UDP port 5060 on devices not configured for SIP. There are no known instances of intentional exploitation of this issue. However, Cisco has observed data streams that appear to be unintentionally triggering the vulnerability.
Workarounds exist to mitigate the effects of this problem on devices which do not require SIP. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20070131-sip.shtml.
CSCec12299 Corruption of ext communities when receiving over ipv4 EBGP sessionSymptom EIGRP-specific Extended Community 0x8800 is corrupted and shown as 0x0:0:0.

CSCsj44099 Router crashes if DSPFARM profile description is 128 characters long.Symptom A cisco c3800 router can experience a memory corruption resulting in a crash if the description field under the "dspfarm profile" configuration matches the maximum of 128 characters.
Conditions During configuration of the dspfarm profile thru the CLI, a description that is 128 characters will cause a memory copy problem. If the user tries to display the results of the configuration using "show dspfarm profile", the router will crash trying to display the output.
Workaround To prevent this problem configure the dspfarm profile description with 127 characters or less.
CSCse24889 Malformed SSH version 2 packets may cause processor memory depletionSymptom Malformed SSH version 2 packets may cause a memory leak, causing the platform to operate under a degraded condition. Under rare circumstances, the platform may reload to recover itself.
Conditions This symptom is observed on a Cisco platform that is configured for SSH version 2 after it has received malformed SSHv2 packets.
Workaround As an interim solution until the affected platform can be upgraded to a Cisco IOS software image that contains the fix for caveat CSCse24889, configure SSH version 1 from the global configuration mode, as in the following example:
config t
ip ssh version 1
end
Alternate Workaround: Permit only known trusted hosts and/or networks to connect to the router by creating a vty access list, as in the following example:
10.1.1.0/24 is a trusted network that is permitted access to the router,all other access is deniedaccess-list 99 permit 10.1.1.0 0.0.0.255access-list 99 deny anyline vty 0 4access-class 99 inendFurther Problem Description: For information about configuring vty access lists, see the Controlling Access to a Virtual Terminal Line document

CSCsd85587A vulnerability has been discovered in a third party cryptographic library which is used by a number of Cisco products. This vulnerability may be triggered when a malformed Abstract Syntax Notation One (ASN.1) object is parsed. Due to the nature of the vulnerability it may be possible, in some cases, to trigger this vulnerability without a valid certificate or valid application-layer credentials (such as a valid username or password).
Successful repeated exploitation of any of these vulnerabilities may lead to a sustained Denial-of-Service (DoS); however, vulnerabilities are not known to compromise either the confidentiality or integrity of the data or the device. These vulnerabilities are not believed to allow an attacker will not be able to decrypt any previously encrypted information.
The vulnerable cryptographic library is used in the following Cisco products:
–Cisco IOS, documented as Cisco bug ID CSCsd85587
–Cisco IOS XR, documented as Cisco bug ID CSCsg41084
–Cisco PIX and ASA Security Appliances, documented as Cisco bug ID CSCse91999
–Cisco Unified CallManager, documented as Cisco bug ID CSCsg44348
–Cisco Firewall Service Module (FWSM)

Open Caveats - Cisco IOS Release 12.4(11)XV
CSCsh40495 On HWIC-3G-GSM and in rare occasions EDGE/GPRS Rx data traffic stops until reset the modemFurther Problem Description: In rare occasions it has been observed that the modem may get into a state where the Rx (Inbound from the Wireless Network to Device) path is blocked. This problem has only been observed when the modem is attached to EDGE service and after a few hours of operation. A modem reset is required to come out of this state.
Workaround As this problem is related to the signal quality at a given location, repositioning the antenna could potentially solve this problem. Using the 20ft or 50ft Cable options, the antenna can be moved out of the spot where interference from multiple cells causes the modem Rx path failure.
When using an attached antenna, relocating the router to a location away from the problem spot can eliminate the problem.
When the failure occurs, a modem reset using the following IOS command would bring the modem out of failure state:
test cellular x/x/x modem-resetCSCse92662:HWIC data path stops workingSymptom :HWIC data path stops working under stress condition. Both transmit and receive directions will be impacted. The problem is not specific to any particular cellular technology
Conditions : Stress over long period of time.
Workaround Reload the router

Actually both licenses are BSD-style Open Source licenses. In case of any license issues related to OpenSSL please contact openssl-core@openssl.org.
