Summary

  • On January 26, 2017, the OpenSSL Software Foundation released a security advisory that included three new vulnerabilities. The foundation also released one vulnerability that was already disclosed in the OpenSSL advisory for November 2016 and included in the Cisco Security Advisory Multiple Vulnerabilities in OpenSSL Affecting Cisco Products: November 2016. OpenSSL classifies all the new vulnerabilities as “Moderate Severity.”

    The first vulnerability affects only OpenSSL used on 32-bit systems architecture and may cause OpenSSL to crash. The second vulnerability affects only version 1.1.0 and occurs only when OpenSSL is used on the client side. The second vulnerability may cause OpenSSL to crash when connecting to a malicious server. The third vulnerability affects only systems based on x86_64 architecture. A successful exploit of the third vulnerability could allow the attacker to access sensitive private key information.

    Multiple Cisco products incorporate a version of the OpenSSL package that is affected by one or more of these vulnerabilities.

    There are no Cisco products affected by the vulnerability identified by CVE ID CVE-2017-3730.

    On February 16, 2017, the OpenSSL Software Foundation released another security advisory that included one high severity vulnerability identified by CVE ID CVE-2017-3733.

    There are no Cisco products affected by this vulnerability.

    This advisory is available at the following link:
    https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20170130-openssl

Affected Products

  • Cisco investigated its product line to determine which products may be affected by these vulnerabilities and the impact on each affected product. Refer to the "Vulnerable Products" and "Products Confirmed Not Vulnerable" sections of this advisory for information about whether a product is affected.

    The "Vulnerable Products" section includes Cisco bug IDs for each affected product. The bugs are accessible through the Cisco Bug Search Tool and contain additional platform-specific information, including workarounds (if available) and fixed software releases.

    There are no Cisco products affected by the vulnerabilities identified by CVE IDs CVE-2017-3730 and CVE-2017-3733.

Details

  • OpenSSL Truncated Packet Processing Denial of Service Vulnerability

    A vulnerability in OpenSSL could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.

    The vulnerability is due to improper processing of truncated packets on an affected 32-bit host system when the system is using a specific cipher. An attacker could exploit this vulnerability by sending a truncated packet to a targeted system. An exploit could trigger an out-of-bounds read condition, causing the system to crash and resulting in a DoS condition.

    OpenSSL Key Exchange Handling Denial of Service Vulnerability

    A vulnerability in OpenSSL could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.

    The vulnerability is due to insufficient validation of user-supplied input processed by the affected software. An attacker could exploit this vulnerability by using a malicious server that is designed to submit crafted parameters for a Diffie-Hellman Key Exchange (DHE) or Elliptic Curve DHE (ECDHE) and persuading a targeted user on a client system to communicate with the malicious server. An exploit could trigger a NULL pointer dereference condition on the client system, causing the system to crash and resulting in a DoS condition.

    OpenSSL Montgomery Squaring Information Disclosure Vulnerability

    A vulnerability in OpenSSL could allow an unauthenticated, remote attacker to access sensitive information on a targeted system.

    The vulnerability is in the x86_64 Montgomery squaring procedure of the affected software. An attacker could exploit this vulnerability by obtaining online access to an unpatched system that uses a shared private key with Diffie-Hellman (DH) parameters set. A successful exploit could allow the attacker to access sensitive private key information.

    OpenSSL Handshake Negotiation Denial of Service Vulnerability

    A vulnerability in OpenSSL could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted system.

    The vulnerability is due to improper security checks by the affected software. An attacker could exploit this vulnerability during a renegotiation handshake by the affected software. If the Encrypt-Then-Mac extension is negotiated during the handshake, the system could stop functioning properly, resulting in a DoS condition on the targeted system.

Workarounds

  • Any workarounds, when available, will be documented in the Cisco bugs, which are accessible through the Cisco Bug Search Tool.

Fixed Software

  • Cisco has released free software updates that address the vulnerabilities described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:
    http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html

    Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.

    When considering software upgrades, customers are advised to consult the Cisco Security Advisories and Responses archive at http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution.

    In all cases, customers should ensure that the devices to upgrade contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.

    Customers Without Service Contracts

    Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco Technical Assistance Center (TAC):
    http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html

    Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.

    To determine the affected and fixed releases for each vulnerable product, refer to the Cisco bug identified for the product in the "Vulnerable Products" section of this advisory. Cisco bugs are accessible through the Cisco Bug Search Tool.

Exploitation and Public Announcements

  • The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerabilities that are described in this advisory.

    A public exploit exists for the OpenSSL Key Exchange Handling Denial of Service Vulnerability, CVE-2017-3730.
