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.

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

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.
