Summary: A 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 previusly encrypted information.
The vulnerable cryptographic library is used in the following Cisco products:
Cisco IOS
Cisco IOS XR
Cisco PIX and ASA Security Appliances
Cisco Firewall Service Module (FWSM)
Cisco Unified CallManager
This vulnerability is assigned CVE ID CVE-2006-3894. It is externally coordinated and is tracked by the following external coordinators:
JPCERT/CC - tracked as JVNVU#754281
CPNI - tracked as NISCC-362917
CERT/CC - tracked as VU#754281
Cisco has made free software available to address this vulnerability for affected customers.
There are no workarounds available to mitigate the effects of the vulnerability.

Summary: Cisco IOS device may crash while processing malformed Secure Sockets Layer (SSL) packets. In order to trigger these vulnerabilities, a malicious client must send malformed packets during the SSL protocol exchange with the vulnerable device.
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 previusly encrypted information.
Cisco IOS is affected by the following vulnerabilities:
* Processing ClientHello messages, documented as Cisco bug ID CSCsb12598
* Processing ChangeCipherSpec messages, documented as Cisco bug ID CSCsb40304
* Processing Finished messages, documented as Cisco bug ID CSCsd92405
Cisco has made free software available to address these vulnerabilities for affected customers.

Posted: May 23, 2007
Summary: This is Cisco PSIRT's response to the statements made by Marc Ruef and Stefan Friedi from scip AG in their message "Cisco CallManager 4.1 Input Validation Vulnerability," posted on 2007 May 23 at 1600 UTC (GMT).
The original emails were posted to BugTraq and Full-Disclosure.
In their postings, Marc Ruef and Stefan Friedi illustrate how to bypass the web application firewall used in Cisco CallManager. This means of bypass can be used to display graphics, scripts, or other information downloaded from an external web site. This technique may also be used to conduct cross-site scripting attacks.
Cisco confirms that the example the authors Ruef and Friedi provided bypasses the web application firewall and that there may be other methods for bypassing the web application firewall.
Cisco has made improvements to the input validation mechanisms in CallManager that may mitigate the risks associated with this security vulnerability. These improvements have been incorporated into 4.2(3)sr2. Future releases, 3.3(5)sr3, 4.1(3)sr5 and 4.3(1)sr1, will also include the improvements made to address this bug.
This issue is being tracked by the following Cisco Bug ID:
CSCsi12374 (registered customers only) —Improvements in User Input Validation
Service releases of CallManager software are available at the following link:

URL:
»www.cisco.com/en/US/customer/pro···bc.shtml
(available to registered users)
Posted: May 31, 2007
Summary: One of the features of the Stream Control Extension (SCX) application enables the user to provide a live video stream while also saving a Windows Media VOD file. An issue was recently discovered that prevented the Windows Media VOD file from being created. The SCX
application will allow you to configure the setting and save the setting. However, the setting will disappear if the operator chooses to edit or examine the encoder settings. The end result of this issue is that the user cannot create a VOD file from an incoming signal. The live stream would be produced as expected. No serial number or date range has been identified.

Cisco Field Notice: Field Notice: FN - 62812 - MWR1941-DC Fan Fa
Title: Cisco Field Notice: Field Notice: FN - 62812 - MWR1941-DC Fan Failures - Replace Unit
URL:
»www.cisco.com/en/US/customer/pro···25.shtml
(available to registered users)
Posted: June 5, 2007
Summary: The content of this field notice is specific to the fans designed for use in the MWR-1941-DC router. No other platforms are covered by this field notice.
The MWR-1941 router fans could contain a defect causing one or more of the system fans to stop spinning or slow to the point prematurely where the system reports a fan failure.
The router should perform as configured providing it has not exceeded the maximum operating temperature. However, system fan failures will reduce the overall airflow and cooling within the box and can result in higher overall operating temperatures.
If the router's internal temperature rises above the maximum operating range, service (network connectivity or application usage) may be impacted depending on environmental conditions. Sustained use of the router beyond the maximum operating temperature could result in permanent damage to the internal components.
