Cisco Security Advisories, Responses, and Notices

Addressing security issues in Cisco products is the responsibility of the Cisco Product Security Incident Response Team (PSIRT). The Cisco PSIRT is a dedicated, global team that manages the receipt, investigation, and public reporting of security vulnerability information that is related to Cisco products and networks.


Please make a note of the Security Vulnerability Policy.

Cisco Security Advisories

Cisco Security Advisories are published for significant security issues that directly involve Cisco products and require an upgrade, fix, or other customer action. In all security publications, Cisco discloses the minimum amount of information required for an end-user to assess the impact of a vulnerability and any potential steps needed to protect their environment. Cisco does not provide vulnerability details that could enable someone to craft an exploit. All security advisories on Cisco.com are displayed in chronological order, with the most recently updated advisory appearing at the top of the page.

Cisco Security Advisories are also available in CVRF format in the CVRF repository.

Cisco Security Advisories pertaining to Cisco IOS Software are also available in OVAL Definition schema in the OVAL repository.

Cisco Security Responses

Cisco Security Responses are published to address less severe problems that affect network security or issues that require a response to information posted to a public discussion forum. They are normally published if a third party makes a public statement about a Cisco product vulnerability that Cisco has previously addressed through our standard disclosure process or when the nature of the issue does not warrant the visibility of a Cisco Security Advisory.

Cisco Security Notices

Cisco Security Notices document low- and medium-severity security issues that directly involve Cisco products but do not warrant the visibility of a Cisco Security Advisory. Cisco Security Notices are organized by Common Vulnerabilities and Exposures (CVE) Identifier to facilitate correlation of security issues across Cisco products. All Security Notices on Cisco.com are displayed in chronological order, with the most recently updated Security Notice appearing at the top of the page.

Latest News

March 14, 2014

In February 2014, Cisco announced details of an industry-wide issue with memory components manufactured by a single supplier between 2005 and 2010. Although the majority of Cisco products that use these components are experiencing field failure rates below expected levels, a device reload or power cycle could expose component failures.


While there are no known security implications associated with this issue, a subset of the affected products may experience a memory component failure during the software upgrade process. Cisco recommends customers review the related information and product-specific field notices at www.cisco.com/go/memory before making upgrade decisions. Each Field Notice indicates whether the product could experience the memory component failure during a software upgrade.
