Note
H.323 Name Display
Note
Calling name display information may be populated in ISDN messages in the Display Information Element (IE) of a Q.931 Setup or Notify message, or in the Facility IE of a Q.931 Setup or Facility message. The Cisco IOS gateway places this information into the same field of the corresponding H.323 message.
Cisco Unified Communications Manager (CUCM) interprets calling name information (for purposes of name display on IP phones registered with CUCM) only in the Display IE of the H.323 Setup and Notify messages. Name display information delivered in an H.323 Facility message is not interpreted by CUCM. Some ISDN switch types (for example, NI2) send a "name-to-follow" indication in the Q.931 Setup message and deliver the calling name subsequently in the Facility IE of a Q.931 Facility message. When a Cisco IOS gateway is connected to such an ISDN switch, and interoperating with CUCM using the H.323 protocol, CUCM is unable to display calling name on the IP phones.
Beginning with Cisco IOS Release 12.4(11)XW, two new modes of operation are introduced on the Cisco IOS gateways:
•
•
This software operation is transparent to CUCM and works with all releases, although CUCM 4.2 or later is recommended.
To enable the H.323 Display feature without buffering for ISDN trunks that use the Facility message to deliver Name Display information, configure the following:
At the voice service level:voice service voiph323h225 display-ie ccm-compatibleAt the voice class level:

Resolved Caveats - Release 12.4(11)XW10
•
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.

•
The 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.
•
A 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.
•
Symptoms: Several features within Cisco IOS software are affected by a crafted UDP packet vulnerability. If any of the affected features are enabled, a successful attack will result in a blocked input queue on the inbound interface. Only crafted UDP packets destined for the device could result in the interface being blocked, transit traffic will not block the interface.
Cisco has released free software updates that address this vulnerability.
Workarounds that mitigate this vulnerability are available in the workarounds section of the advisory. This advisory is posted at the following link: http://www.cisco.com/warp/public/707/cisco-sa-20090325-udp.shtml.

Cisco IOS software contains two vulnerabilities within the Cisco IOS WebVPN or Cisco IOS SSLVPN feature (SSLVPN) that can be remotely exploited without authentication to cause a denial of service condition. Both vulnerabilities affect both Cisco IOS WebVPN and Cisco IOS SSLVPN features:

Cisco has released free software updates that address these vulnerabilities. There are no workarounds that mitigate these vulnerabilities. This advisory is posted at the following link: http://www.cisco.com/warp/public/707/cisco-sa-20090325-webvpn.shtml
•
Symptoms: SSLVPN service stops accepting any new SSLVPN connections.
Conditions: A device configured for SSLVPN may stop accepting any new SSLVPN connections, due to a vulnerability in the processing of new TCP connections for SSLVPN services. If "debug ip tcp transactions" is enabled and this vulnerability is triggered, debug messages with connection queue limit reached will be observed. This vulnerability is documented in two separate Cisco bug IDs, both of which are required for a full fix: CSCso04657 and CSCsg00102.

Cisco IOS software contains two vulnerabilities within the Cisco IOS WebVPN or Cisco IOS SSLVPN feature (SSLVPN) that can be remotely exploited without authentication to cause a denial of service condition. Both vulnerabilities affect both Cisco IOS WebVPN and Cisco IOS SSLVPN features:
1.
2.
Cisco has released free software updates that address these vulnerabilities. There are no workarounds that mitigate these vulnerabilities. This advisory is posted at the following link: http://www.cisco.com/warp/public/707/cisco-sa-20090325-webvpn.shtml

Multiple 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.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080924-sip.shtml.
•
The Secure Shell server (SSH) implementation in Cisco IOS contains multiple vulnerabilities that allow unauthenticated users the ability to generate a spurious memory access error or, in certain cases, reload the device.
The IOS SSH server is an optional service that is disabled by default, but its use is highly recommended as a security best practice for management of Cisco IOS devices. SSH can be configured as part of the AutoSecure feature in the initial configuration of IOS devices, AutoSecure run after initial configuration, or manually. Devices that are not configured to accept SSH connections are not affected by these vulnerabilities.
Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1159 has been assigned to this bug.
