Open Caveats - Release 12.4(15)XZ2
There are no open caveats in this release.
Resolved Caveats - Release 12.4(15)XZ2
•
Multiple Cisco products are affected by denial of service (DoS) vulnerabilities that manipulate the state of Transmission Control Protocol (TCP) connections. By manipulating the state of a TCP connection, an attacker could force the TCP connection to remain in a long-lived state, possibly indefinitely. If enough TCP connections are forced into a long-lived or indefinite state, resources on a system under attack may be consumed, preventing new TCP connections from being accepted. In some cases, a system reboot may be necessary to recover normal system operation. To exploit these vulnerabilities, an attacker must be able to complete a TCP three-way handshake with a vulnerable system.
In addition to these vulnerabilities, Cisco Nexus 5000 devices contain a TCP DoS vulnerability that may result in a system crash. This additional vulnerability was found as a result of testing the TCP state manipulation vulnerabilities.
Cisco has released free software updates for download from the Cisco website that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090908-tcp24.shtml.
CSCsr16693A series of TCP packets may cause a denial of service (DoS) condition on Cisco IOS devices that are configured as Easy VPN servers with the Cisco Tunneling Control Protocol (cTCP) encapsulation feature. Cisco has released free software updates that address this vulnerability. No workarounds are available; however, the IPSec NAT traversal (NAT-T) feature can be used as an alternative.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090325-ctcp.shtml.
Note: The March 25, 2009, Cisco IOS Security Advisory bundled publication includes eight Security Advisories. All of the advisories address vulnerabilities in Cisco IOS Software. Each advisory lists the releases that correct the vulnerability or vulnerabilities in the advisory. The following table lists releases that correct all Cisco IOS Software vulnerabilities that have been published in Cisco Security Advisories on March 25, 2009, or earlier.

http://www.cisco.com/en/US/products/products_security_advisories_listing.html
CSCsv38166The server side of the Secure Copy (SCP) implementation in Cisco IOS software contains a vulnerability that could allow authenticated users with an attached command-line interface (CLI) view to transfer files to and from a Cisco IOS device that is configured to be an SCP server, regardless of what users are authorized to do, per the CLI view configuration. This vulnerability could allow valid users to retrieve or write to any file on the device's file system, including the device's saved configuration and Cisco IOS image files, even if the CLI view attached to the user does not allow it. This configuration file may include passwords or other sensitive information.
The Cisco IOS SCP server is an optional service that is disabled by default. CLI views are a fundamental component of the Cisco IOS Role-Based CLI Access feature, which is also disabled by default. Devices that are not specifically configured to enable the Cisco IOS SCP server, or that are configured to use it but do not use role-based CLI access, are not affected by this vulnerability.
This vulnerability does not apply to the Cisco IOS SCP client feature.
Cisco has released free software updates that address this vulnerability.
There are no workarounds available for this vulnerability apart from disabling either the SCP server or the CLI view feature if these services are not required by administrators.
This advisory is posted at the following link:
http://www.cisco.com/warp/public/707/cisco-sa-20090325-scp.shtml.
CSCsu11522A vulnerability exists in the Session Initiation Protocol (SIP) implementation in Cisco IOS software that can be exploited remotely to cause a reload of the Cisco IOS device.
Cisco has released free software updates that address this vulnerability. There are no workarounds available to mitigate the vulnerability apart from disabling SIP, if the Cisco IOS device does not need to run SIP for VoIP services. However, mitigation techniques are available to help limit exposure to the vulnerability.
This advisory is posted at the following link:
http://www.cisco.com/warp/public/707/cisco-sa-20090325-sip.shtml.
CSCsr29468Cisco IOS software contains a vulnerability in multiple features that could allow an attacker to cause a denial of service (DoS) condition on the affected device. A sequence of specially crafted TCP packets can cause the vulnerable device to reload.
Cisco has released free software updates that address this vulnerability.
Several mitigation strategies are outlined in the workarounds section of this advisory.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090325-tcp.shtml
CSCsq09424 Few headers are duplicated when configured in passthru-hdr list and pass.Symptom In a CUBE, when headers may be passed through from the incoming side of a call to the outgoing side, there are certain headers which may be added multiple times.
Conditions
Workaround
Further Problem Description: This problem occurs because a header is being passed through a CUBE from the OGW to the TGW in an IP-IP call. This results in outgoing SIP messages which are syntactically invalid, and may result in failures depending on the SIP implementation on the receiving end.
CSCsr78883 Router console displays messages "Data corruption Data Inconsistency.Symptom There will be traceback on configuring mls qos cos pass-through dscp in supporting interface mode.
Conditions
Workaround
Further Problem Description: Due the buffer overflow, there will be traceback when configuring the QoS in the supporting interface. Currently, the CLI is not supported in the most network modules, and thus, invisible to the users.
CSCsr06874 2800 periodically crash on CMM_CRS functions.Symptom Periodical crashes on 2800 with CME features.
Conditions
Workaround
CSCsq50366 Last digit getting truncated when prefix is set to its max value of 32.Symptom Last digit getting truncated when prefix is configured with a length of 32 under the dial-peer.

Conditions
Workaround
CSCso58935 Caller ID still display Barge for point-to-point call between sccp share.Symptom Caller ID still display To Barge for point to point call between two sccp shared line phones after the other party drops out from cBarge conference.
Workaround
CSCsr14658 CLI Cannot handle Double quotes.Symptom CME 4.3. IOS 12.4.15XZ SP Services. Under telephony-service the following url services was configured:
http://10.1.1.1 "My service"
Note the quotes. On the running config you see the above command without the quotes and everything works fine. When you type wr, then you again see the same command without the quotes. The issue is that, when you reload the router, the command is there, but it is not accepted and you have to type it again. Also, if you type url services http://10.1.1.1 My service, then you get an error of invalid input.
Conditions
Workaround
CSCsq48167 CME DN description command may allow for open-ended quote delimination.Symptom The CME description command under the ephone-dn potentially allows for the description string to be saved to the router configuration without a trailing quote. This leaves an open-ended delimination in the configuration for the description string, and will cause the CME GUI to fail to load with an "unterminated string constant" error.
Conditions

Conditions
The Max-Forwards header field must be used with any SIP method to limit the number of proxies or gateways that can forward the request to the next downstream server. This can also be useful when the client is attempting to trace a request chain that appears to be failing or looping in mid-chain. The Max-Forwards value is an integer in the range 0-255 indicating the remaining number of times this request message is allowed to be forwarded. This count is decremented by each server that forwards the request. The recommended initial value is 70. This header field should be inserted by elements that can not otherwise guarantee loop detection. For example, a B2BUA should insert a Max-Forwards header field.

Workaround
Further Problem Description: This can impact customers that use the Embedded Event Manager with EEM applets or policies that interact with the CLI. It was seen on the ASR platform and other platforms when "sched heapchecks process" was enabled. A timing issue can cause EEM action CLI commands to not coordinate with the IOS exec properly.The SIP2 is probably related to the ASR platform. An OIR event issued to trigger the specific EEM policy. This should occur with any EEM type policy however.
SXF is not impacted by this bug.

CSCsl62609Multiple vulnerabilities exist in the Session Initiation Protocol (SIP) implementation in Cisco IOS that can be exploited remotely to trigger a memory leak or to cause a reload of the Cisco IOS device.
Cisco has released free software updates that address these vulnerabilities. Fixed Cisco IOS software listed in the Software Versions and Fixes section contains fixes for all vulnerabilities addressed in this advisory.
There are no workarounds available to mitigate the effects of any of the vulnerabilities apart from disabling the protocol or feature itself, if administrators do not require the Cisco IOS device to provide voice over IP services.
