Cisco Security Advisories, Responses, and Alerts

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. This document also contains instructions for Receiving Security Vulnerability Information from Cisco.

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 Alerts

Cisco Security Alerts 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 Alerts are organized by Common Vulnerabilities and Exposures (CVE) Identifier to facilitate correlation of security issues across Cisco products. All Security Alerts on Cisco.com are displayed in chronological order, with the most recently updated Security Alerts appearing at the top of the page.

Latest News

Announcing the First Cisco IOS and IOS XE Software Security Advisory Bundled Publication

On March 25, 2015, the first Cisco IOS and IOS XE Software Security Advisory Bundled Publication was released. As a reminder, Cisco has disclosed vulnerabilities in Cisco IOS Software on a predictable schedule (the fourth Wednesday of March and September each calendar year). In direct response to customer feedback, a Cisco Security Advisory addressing vulnerabilities in Cisco IOS XE Software has also been included in this publication. Cisco PSIRT hopes this timeline and additional "bundling" continues to help organizations plan and ensure resources are available to analyze, test, and remediate vulnerabilities in their environments; please consult each individual Security Advisory to determine if Cisco IOS XE Software is affected by any disclosure vulnerability.

For a high-level overview, please review the blog post and Cisco Event Response--our go-to document that correlates the full array of Cisco Security resources for this bundle (including links to the advisories, mitigations, Cisco IntelliShield Alerts, CVSS scores, and OVAL content).

Before the last bundled publication, Cisco announced enhancements to the Cisco IOS Software Checker. The tool is now capable of displaying first-fixed software release data based on the combination of Cisco IOS Software releases and Cisco Security Advisories selected. Users can now quickly identify the first release that addresses all vulnerabilities disclosed in the selected advisories. The Cisco IOS Software Checker is updated daily to include the most up-to-date information on recent Cisco IOS Software releases. Cisco recommends that interested parties query the enhanced tool now, or review the table below for a quick status update on our major Cisco IOS Software trains. At least one software release in every train listed below is vulnerable to the recently disclosed vulnerabilities:
