CSCsh58082 SIP: A router may reload due to SIP trafficSymptom Cisco 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.
Workaround
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20070131-sip.shtml.

CSCsg40567 Memory leak found with malformed tls/ssl packets in http core processSymptom Malformed SSL packets may cause a router to leak multiple memory blocks.
Conditions
Workaround
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.
CSCsg16908 IOS FTP Server DeprecationMultiple vulnerabilities exist in the Cisco IOS File Transfer Protocol (FTP) Server feature. These vulnerabilities include Denial of Service, improper verification of user credentials and the ability to read or write any file in the device's file system, including the device's saved configuration, which may include passwords or other sensitive information.
The IOS FTP Server is an optional service that is disabled by default. Devices that are not specifically configured to enable the IOS FTP Server service are unaffected by these vulnerabilities.
This vulnerability does not apply to the IOS FTP Client feature.
This advisory is posted at
http://www.cisco.com/warp/public/707/cisco-sa-20070509-iosftp.shtml.
CSCsi01470A vulnerability in the Cisco implementation of Multicast Virtual Private Network (MVPN) is subject to exploitation that can allow a malicious user to create extra multicast states on the core routers or receive multicast traffic from other Multiprotocol Label Switching (MPLS) based Virtual Private Networks (VPN) by sending specially crafted messages.
Cisco has released free software updates that address this vulnerability. Workarounds that mitigate this vulnerability are available.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-mvpn.shtml.
CSCsi84017 c2600 router hangs during reloadSymptom When you reload a Cisco 2600 series, the router may hang.
Conditions
Workaround
CSCsi09530 CME SIP phone failed to register because of authenticate registerSymptom If the authenticate register command is configured under the voice register global command, CME SIP failed to registered.
Conditions
Workaround
Further Problem Description: In registrar functionality, CME challenges an inbound register request with a 401 response. If the authenticate register command is configured under the voice register global command, the Registering Endpoint then ends a Register Request with Credentials. The Gateway Stack is not processing this request and is dropping it.
CSCsf07847 cdp may fail to discover neighbor information in releases with CSCse85200Symptom Specifically crafted CDP packets can cause a router to allocate and keep extra memory. Exploitation of this behavior by sending multiple specifically crafted CDP packets could cause memory allocation problems on the router.
Conditions
Workaround
Further Problem Description: Because CDP is a Layer-2 protocol, the symptom can only be triggered by routers that reside on the same network segment.
CSCsj32707 GW rejects SIP UPDATE with Cseq 0Symptom A "SIP UPDATE" message from a Cisco CallManager or SIP Proxy Server with a "Cseq" value of 0 may be rejaected or considered invalid by A Cisco gateway.
Conditions
Workaround
CSCsj44081 Improvements in diagnostics and instrumentationCisco IOS Software has been enhanced with the introduction of additional software checks to signal improper use of internal data structures. This enhancement was introduced in select Cisco IOS Software releases published after April 5, 2007.
Details: With the new enhancement in place, IOS will emit a %DATACORRUPTION-1-DATAINCONSISTENCY error message whenever it detects an inconsistency in its internal data structures. This is a new error message. The following is an example.
The %DATACORRUPTION-1-DATAINCONSISTENCY error message is preceded by a timestamp
May 17 10:01:27.815 UTC: %DATACORRUPTION-1-DATAINCONSISTENCY: copy errorThe error message is then followed by a traceback.
It is important to note that this error message does not imply that packet data is being corrupted. It does, however provide an early indicator of other conditions that can eventually lead to poor system performance or an IOS restart.
Recommended Action Collect "show tech-support" command output and open a service request with the Technical Assistance Center (TAC) or designated support organization. Pay particular attention to any other error messages or error symptoms that accompany the %DATACORRUPTION-1-DATAINCONSISTENCY message and note those to your support contact.

Resolved Caveats - Cisco IOS Release 12.4(6)XE2
CSCsf04754: Two authentication vulnerabilities in SNMPv3 featureSymptom Multiple Cisco products contain either of two authentication vulnerabilities in the Simple Network Management Protocol version 3 (SNMPv3) feature. These vulnerabilities can be exploited when processing a malformed SNMPv3 message. These vulnerabilities could allow the disclosure of network information or may enable an attacker to perform configuration changes to vulnerable devices. The SNMP server is an optional service that is disabled by default. Only SNMPv3 is impacted by these vulnerabilities.
Workaround
CSCse06975: Traceback at pak_copy_contiguous_to_contiguous when testing multicastSymptom VoIP LMR multicast capability does not work on network module NM-HD-2V with E&M.
Workaround
CSCse15025: Intermittent analog/cas voice port lockup or robotic voiceSymptom An analog or digital CAS port enters a state in which inbound or outbound calls, or both, may no longer function through the port.
Conditions
When this problem occurs, it impacts multiple ports that share the same signaling DSP. The output of the show voice dsp signaling EXEC command shows which DSP is used by a port for signaling. The symptom may occur more often for ports that use DSP 1 on the PVDM2 module for signaling.
Because this issue impacts the signaling channels, it has been seen that calls either will not connect at all through impacted ports or in some cases when multiple simultaneous calls are present on adjacent voice ports/timeslots, the call may connect momentarily before being disconnected.
If a problem occurs only on a single voice port, there is another problem, not this caveat (CSCse15025). PRI/BRI calls are not affected because PRI/BRI does not utilize the DSP for signaling purposes.
When the symptom occurs with either a VIC2-xFXO or EVM DID/FXS module, enter the terminal monitor command followed by the test voice port port-number si-reg-read 39 1 command for one of the affected ports. The output typically should be a single octet value for register 39. When the symptom occurs, information for Registers 40, 41, and 42 is presented and some of the registers show double- octet information.
When the symptom occurs with FXS or analog E&M modules, enter the terminal monitor command followed by the test voice port port- number codec-debug 10 1 command for one of the affected ports. The output typically should be a single octet value for each register.
Workaround
Further Problem Description The changes in CSCse15025 includes changes in CSCsc11833 and CScsd90851. These changes have been shown to help mitigate this problem in the majority of cases.
There is a further detection and reset mechanism in CSCse15025 that will recover the DSP which is in this state. This mechanism will trigger immediately if the impacted voice port is an analog FXO port. For other voice ports, a delay in the detection will be present and it is possible to see the symptom of this problem before the recovery code triggers.
Note that the reset mechanism will cause any active calls utilizing the DSP in question to be dropped. It is recommended if running with modules which can be impacted by this issue to upgrade to a release of software which contains the changes in CSCse15025.
If the DSP is reset and the below output is seen, contact the TAC for further assistance. Note that this output is sent at debug level and it is recommended to enable either syslog or logging buffered on the gateway.
Logging buffered on the gateway is enabled through the global command logging buffered 50000 debug as an example to set the logging buffered to use 50K bytes of processor memory for logging. The output of the log can be seen with the exec command show log.

NHRP Bugs in IP Routing Protocols
•
The Cisco Next Hop Resolution Protocol (NHRP) feature in Cisco IOS contains a vulnerability that can result in a restart of the device or possible remote code execution.
NHRP is a primary component of the Dynamic Multipoint Virtual Private Network (DMVPN) feature.
NHRP can operate in three ways: at the link layer (Layer 2), over Generic Routing Encapsulation (GRE) and multipoint GRE (mGRE) tunnels and directly on IP (IP protocol number 54). This vulnerability affects all three methods of operation.
NHRP is not enabled by default for Cisco IOS.
This vulnerability is addressed by Cisco bug IDs CSCin95836 for non-12.2 mainline releases and CSCsi23231 for 12.2 mainline releases.

SCP Bugs in 12.4(6)XE
•
The server side of the Secure Copy (SCP) implementation in Cisco IOS contains a vulnerability that allows any valid user, regardless of privilege level, to transfer files to and from an IOS device that is configured to be a Secure Copy server. This vulnerability could allow valid users to retrieve or write to any file on the device's filesystem, including the device's saved configuration. This configuration file may include passwords or other sensitive information.
The Cisco IOS Secure Copy Server is an optional service that is disabled by default. Devices that are not specifically configured to enable the Cisco IOS Secure Copy Server service are not affected by this vulnerability.
This vulnerability does not apply to the Cisco IOS Secure Copy Client feature.

IPv6 Bugs in 12.4(6)XE
•
Cisco IOS and Cisco IOS XR contain a vulnerability when processing specially crafted IPv6 packets with a Type 0 Routing Header present. Exploitation of this vulnerability can lead to information leakage on affected Cisco IOS and Cisco IOS XR devices, and may also result in a crash of the affected Cisco IOS device. Successful exploitation on an affected device running Cisco IOS XR will not result in a crash of the device itself, but may result in a crash of the IPv6 subsystem.
Cisco has made free software available to address this vulnerability for affected customers. There are workarounds available to mitigate the effects of the vulnerability.
