The Common Vulnerabilities and Exposures (CVE) IDs and names of the vulnerabilities that were disclosed on November 10, 2016, in the OpenSSL Software Foundation security advisory are as follows:
- CVE-2016-7053: OpenSSL CMS Null Dereference Vulnerability
- CVE-2016-7054: OpenSSL ChaCha20/Poly1305 Heap Buffer Overflow Vulnerability
- CVE-2016-7055: OpenSSL Montgomery Multiplication May Produce Incorrect Results Vulnerability
OpenSSL CMS Null Dereference Vulnerability
A vulnerability in the code that handles ASN.1 CHOICE type in OpenSSL 1.1.0 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.
The vulnerability is due to a NULL value being passed to the structure callback if an attempt is made to free certain invalid encodings. An attacker could exploit this vulnerability by submitting crafted input to be processed by the affected software. A successful exploit could allow an attacker to cause the application to stop functioning properly, leading to a DoS condition.
This vulnerability has been assigned the following CVE ID: CVE-2016-7053
OpenSSL ChaCha20/Poly1305 Heap Buffer Overflow Vulnerability
A vulnerability in the *-CHACHA20-POLY1305 cipher suites in OpenSSL could allow an unauthenticated, remote attacker to cause a targeted system to crash, resulting in a denial of service (DoS) condition.
The vulnerability is due to improper validation of user-supplied data by the affected software. An attacker could exploit this vulnerability by submitting large amounts of crafted data to the *-CHACHA20-POLY1305 cipher suites of the affected software over a Transport Layer Security (TLS) connection. A successful exploit could allow the attacker to cause the affected software to crash, resulting in a DoS condition on the targeted system.
This vulnerability has been assigned the following CVE ID: CVE-2016-7054
OpenSSL Montgomery Multiplication May Produce Incorrect Results Vulnerability
A vulnerability in OpenSSL could cause authentication or key negotiation failures, resulting in a denial of service (DoS) condition.
The vulnerability is due to Montgomery multiplication mathematical errors that occur when using OpenSSL with elliptic curve algorithms. The vulnerability may occur without any external attacker action when performing cryptographic operations. Errors resulting from incorrect mathematical computations could cause OpenSSL to fail during authentication or key negotiation, resulting in a DoS.
This vulnerability has been assigned the following CVE ID: CVE-2016-7055
For additional details about the vulnerabilities, refer to the November 2016 OpenSSL Security Advisory published by the OpenSSL Software Foundation.
-
Any workarounds that address one or more of these vulnerabilities will be documented in the Cisco bugs, which are accessible from the Cisco Bug Search Tool, for each affected product.
-
Updates for affected software releases will be published when they are available and information about those updates will be documented in Cisco bugs, which are accessible from the Cisco Bug Search Tool.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page, to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded 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.
