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:

Open Caveats - Cisco IOS Release 12.4(11)XJ
There are no open caveats in this release.
Resolved Caveats - Cisco IOS Release 12.4(11)XJ
CSCse89321: DTMF path not getting confirmed in sip media forking callSymptom There is no end-to-end DTMF path confirmation.
There is no workaround.
CSCsf26561: User portion of Diversion header is incorrect when calling through AASymptom Tests on customer setup have revealed that PSTN to AA --> tx to SCCP phone--> CFWD to CUE/PSTN has an issue. The 302 Moved Temporarily from CME to BroadSoft has a Diversion header whose user portion is the private extension #, not the expanded DID # due to which the subsequent call fails.
Workaround
CSCsf32028: Host portion of Refer-To: header must be an Address of RecordSymptom SIP trunking environments (for example, Cbeyond) need the URIs to carry Address of Record [AOR] in many SIP headers.
Workaround
CSCsg17289: DNS-SRV issues for SIP registrationsSymptom Registrar, both the dial-peers would try to send a REGISTER request sequentially. When first Dial-peer (D1) is sending REGISTER Request, the registrar cache is empty. It first sends a DNS query (SRV). After getting the DNS Response, it updates the Registrar cache and sends the REGISTER request to Registrar R1. dns_count variable here is set to SIP_DNS_MODE.
When second dial-peer is sending REGISTER request, it finds the resolved IP address in registrar cache (R1) so it sends the REGISTER request to R1. dns_count variable here is set to SIP_NON_DNS_MODE. But both the REGISTER request fails as R1 is down.
As D1 is set to SIP_DNS_MODE, D1 would send a DNS query again with incremented dns_count to get any alternate Registrar and it gets R2. It sends REGISTER request to R2 and gets successfully registered. As D2 is set to SIP_NON_DNS_MODE, it does not retry the DNS query and simply backs off for period REG_EXPIRES/20.
Workaround
CSCsg18902: Blind transfer is not working on SIP trunkSymptom Blind transfer failed on SCCP endpoint over SIP trunk
Conditions
Workaround
CSCsg30101:CME: dtmf-relay force rtp-nte CLI does not workSymptom The voice-class sip dtmf-relay force rtp-nte command does not work.
Conditions
As a result, rfc2833 is not negotiated and hence DTMF is sent raw inband. When PSTN caller presses DTMF digits after being prompted by AA, nothing works, since the CME cannot convert raw-inband DTMF to NOTIFY. With 12.4-4T3 the CME replied to the PSTN gw with g711u and rfc2833(PT=101).
Workaround
CSCsg39750: Spurious mem access/traceback while resetting sip phone with presenceSymptom Spurious memory access and traceback is encountered while resetting the SIP phone (7961). After configuring presence with CME.BLF speed dial entries, the status is not updated for the watched phones.
Workaround
CSCsg46362: contact header incorrect in 302 message using sip-srst redirect modeSymptom The contact header ip address is incorrect in the 302 message sent by SIP SRST in redirect mode. As the result basic call fails in this mode. B2b mode is working okay.
Workaround
CSCsg46411: CME does not send a REFER over SIP trunk for calls involving AASymptom CME fails to send a REFER over the SIP trunk for calls coming into the CUE-AA and being transferred to a local extension.
Conditions
Workaround
CSCsg51244: CME does not send 3xx messages for transfer --> forward scenariosSymptom CME does not send a 3xx message during call fwd if there was a call-transfer invoked before the call-forward happens.
Conditions
Workaround
CSCsg51259: DTMF stops working after consult transfer to called party mailboxSymptom PSTN connects to extension A, A transfers to B, B's CUE voicemail answers due to CFNA, A does a full consult transfer to B's CUE voicemail.
Conditions
Workaround
CSCek61666: Ephone DNs get stuck in SEIZE state under certain conditionsSymptom Ephone DNs gets stuck in seize state under certain conditions, particularly under the following sequence:
1. phone-A has multiple trunk-DNs configured.2. Call comes in on one of trunk-DN, say DN1. Call is answered and thetransfer button is pressed and another extension (DN3) is dialed.The dialed extension answers the call.3. At this time, the user on phone-A goes offhook on another trunk DN(say DN2), and dials one digit.4. The PSTN user who is connected to DN1 hangs up and so does DN3The above sequence gets both channels of DN1 into SEIZE state.
Conditions
Workaround
CSCek37305: Cisco 7200 router crashes at get_hwidb_if_sameSymptom Router crashes on unconfiguring T1 controller with interface configured for RTP priority.
Conditions
Workaround
CSCek39470: Router memory leak due to pak subblock chunk leaking with crypto+BVISymptom Cisco IOS router running 12.4 may experience per packet memory leak due to pak subblock leak in Process memPool (not in IO mem pool). The symptom is: show proc mem 1 output seeing the first allocator's memory count is keep growing, and never decrease.
Conditions
Workaround
CSCek45272: NAT overload failing with static mappingsSymptom NAT overloading from inside source address to an outside interface may fail.
Conditions
Workaround
CSCek61570: Trunk dn stuck in seize/seize state and does not recoverSymptom The ephone DN may get stuck in SEIZED state and one-way audio would occur afterwards.
Conditions
Workaround
CSCek62099: MLP: PPPoE encap not applied to CEF switched non-MLP packetsSymptom When PPP Multilink is enabled over a PPP over Ethernet (PPPoE) session, outbound packets are incorrectly sent without PPPoE headers. This causes them to be dropped.
Conditions
Workaround
CSCir00074: Router crashes when casnDisconnect is set to true for pppoe sessionSymptom A router crashes when the casnDisconnect object is set to "true" for a PPPoE session.
Conditions
Workaround
CSCir00530: CJ-Ph2:Entry missing in cefcModuleTable for a CJ PA in Escort slotSymptom Entry for Crackerjack PA missing from cefcModuleTable.

Conditions
Workaround
CSCsf27796: 1841 router reloads at retparticle with %SYS-2-BADSHARE errorSymptom A 1841 router may reload at retparticle with %SYS-2-BADSHARE errors.
Conditions
Workaround
CSCsg02881: MLP: Bandwidth of down MLP group should be sum of member bandwidthsSymptom The bandwidth of a multilink group interface that is down does not reflect the actual bandwidths of the links that are configured as members of the multilink group. In Cisco IOS Release 12.4(8) and later, the multilink interface bandwidth reflects the bandwidth of the last link in the bundle prior to going down. In earlier versions, the bandwidth is restored to 100000 Kbps.
Conditions
Workaround
CSCsg10159: Successive Default route ctrl fails on different link but on same routerSymptom default route withdrawn message is send from BR immediately after successful control of default roue. And prefix goes to DEFAULT state.
Conditions
Workaround
CSCsg12813: Speech loss after receiving MDCX from PGWSymptom Cisco AS5400 gateway may change it's RTP sequence numbers after receiving a MDCX command. The RTP Stream SSRC is always the same but the Sequence Number seems to be randomly initiated again.
Conditions
Workaround

CSCsg16748: ABR deletes OSPF type 3 LSA after it received max-aged type 2 LSASymptom In the situation ABR has both type 2 LSA and type 1 LSA for a prefix, ABR deletes type 3 LSA if it received max-aged type 2 LSA.
Workaround
CSCsg33172: IPS 5.0: Provide more informational error message XML and namesSymptom A few inconsistent error message.
Conditions
Workaround
CSCsg38907: rip - redistribute static: redistributed prefixes have metric 16Symptom Under some conditions redistributed static routes are sent out with metric 16
Conditions
Workaround
CSCsg39216: ezvpn tunnel traffic with acl keyword is not excluded from NATSymptom When EZVPN client is configured with "acl" keyword, the tunneled (vpn) traffic also gets NATed.
Conditions
Example:
crypto ipsec client ezvpn hwclientconnect autogroup cisco key cisco123mode network-extensionpeer 10.1.1.1acl 103access-list 103 permit ip 192.168.100.0 0.0.0.255 192.168.1.0 0.0.0.255
This occurs when the following is true:
1) ezvpn client is configured
2) interesting tunnel traffic is defined using the "acl" keyword under global ezvpn configuration
3) NAT is configured
Workaround
CSCsg39961: crash sending pki request to CA CSCsg43460 Improve NPE-G2 ENVM handlingSymptom A router may unexpectedly reload when trying to send a PKI request to a CA.
Conditions
Workaround
CSCsg46546: Erroneous alerting during pickup with CSCek58324 scenarioSymptom Pickup will result in alerting from the pickup target instead of connected.
Conditions
Workaround
CSCsg47834: NACK is observed for Open voice channel commandSymptom NACK message may be received from 5510 DSP in response to Open Voice Channel command sent by the Cisco IOS software.
2568288: Oct 24 13:11:33.240: //-1/xxxxxxxxxxxx/HPI/[]/hpi_tx_global_debug_info:DSP 3/0x3 port INVALID_CHANNEL_STATE(85), info 0x01(1)DSP 3/0x00000003 port mode CLOSED(1), state UNDEFINED(133), NACKed message 74/0x4A @0DSP message header 0008 0003 004A 0001 Payload: 0x0000 0x0000 0xFFFF 0x0000Conditions
Workaround
1) Disable Transcoding
(or)
2) Make sure that the Transoding and Voice Termination are on different DSP(s).
This can be performed by configuring the maximum number of transcoding sessions to a value such that it would require a multiple of 240 DSP credits.
Example 1:
In the following configuration each transcoding session (complexity=high) will require 40 DSP credits. In order to use a multiple of 240 credits, we need to set the maximum transcoding sessions to 6 (6 * 40 = 240) or any multiple of 6.
dspfarm profile 1 transcodecodec g711ulawcodec g729r8associate application SCCPRouter(conf-t)#dspfarm profile 1 transcodeRouter(config-dspfarm-profile)#maximum sessions 6Example 2:
In the following configuration each transcoding session (complexity=medium) will require 30 DSP credits. In order to use a multiple of 240 credits, we need to set the maximum transcoding sessions to 8 (8 * 30 = 240) or any multiple of 8.
dspfarm profile 2 transcodecodec g711ulawcodec g711alawcodec g729ar8codec g729abr8associate application SCCPRouter(conf-t)#dspfarm profile 2 transcodeRouter(config-dspfarm-profile)#maximum sessions 8Use show voice dsp group all command to verify DSP resource allocation.
Note: Each 5510 DSP has 240 Credits. This work-around cannot be implemented if the router has only one PVDM2-16 which has only one DSP.
CSCsg48183: Unforeseen ARP request send from all interfacesSymptom A router may unexpectedly send an ARP request from all its active interfaces to the nexthop of the network of an SNMP server.

If Phone-A goes offhook on DN-1 and Phone-B immediately goes offhook on DN-2. This condition should show the DN-2 button on Phone-A as busy which is not happening.
Conditions
Workaround
CSCsg68711: Incoming call in background does not audibly ring after transfer commitSymptom Phone does not ring for the second incoming call after committing transfer at alert for the first call.
Conditions
Workaround
CSCsg70221: DTMF through the hairpin of a trunk DN does not workSymptom DTMF tones are being suppressed to prevent duplicate DTMF tones from being extended to an SCCP controlled VG224 port. This problem is direct result of a fix implemented for correct CSCsf98754. The lack of DTMF prevents IVR devices from working correctly
Conditions
A call comes into a FXO port that is part of a trunk group and gets transferred to an extension that is hanging off of a vg224. DTMF is not relayed to the end point
Workaround
CSCsg70355: Adopt new default summer-time rules from Energy Policy Act of 2005Symptom Starting in calendar year 2007, daylight savings summer-time rules may cause Cisco IOS to generate timestamps (such as in syslog messages) that are off by one hour.
