Vulnerability Disclosure Policy
Cybersecurity is most successful when it is built into the development and delivery of products, applications, and platforms. We also recognize that there is no silver bullet solution to security and welcome contributions from external security researchers, industry organizations, vendors, and other sources concerned with cybersecurity.
Responsible Disclosure Guidelines
To promote the discovery and reporting of vulnerabilities in our products, and to ensure safety for users of our products, reporters must adhere to the following guidelines for submission of any potential vulnerabilities:
- Share security issues with Synopsys confidentially, with sufficient information to evaluate the submission (recommended details below)
- Do not make any information public without Synopsys’ guidance and consent
- Do not access or modify any user data in any application (regardless of whether that data belongs to Synopsys or an end user of the application). Only interact with your own accounts or test accounts for security research purposes
- Contact Synopsys within 24 hours if you encounter any end user data. Do not view, alter, save, store, transfer, or otherwise access the data, and immediately purge any local information upon reporting the vulnerability to Synopsys
- Always act in good faith so as to avoid violations to applicable laws, the destruction of data, or the interruption or degradation of our services (including denial of service)
- Comply with all applicable laws
We will not negotiate in response to duress or threats. We will not negotiate under threat of withholding the vulnerability or threat of releasing the vulnerability or any exposed data to the public.
Reporting a Potential Security Vulnerability
If you observe a potential security vulnerability in one of our products, you are strongly encouraged to contact Synopsys to report it and include the following details when reporting a potential security vulnerability:
- Affected Product/Platform and Version
- Technical description of the issue
- Detailed steps to reproduce and/or sample code used to exploit the vulnerability
- Contact information and optional name for acknowledgments
- Proposed disclosure plans
Excluded Submission Types
- Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks
- Findings generated by automated tools without detailed explanation on what parts are vulnerable and how the vulnerability might be exploited
Synopsys prefers all reports of potential security vulnerabilities for Synopsys products or software are encrypted using the PGP/GNU Privacy Guard (GPG) public key found below. Please report any potential security vulnerabilities in Synopsys products or software to the following email address: psirt@synopsys.com.
PGP Key File: public_key.asc
PGP Key Fingerprint: A372 BE54 6549 A2D5 D26E DB81 4E5B E854 E9B9 A073
Please note that the PSIRT contact addresses should only be used for reporting undisclosed security vulnerabilities in our products, applications, and platforms, and for managing the process of fixing such vulnerabilities. If you’d like to make a general support request, please use the official support channel. All mail sent to this address that does not relate to an undisclosed security vulnerability will be destroyed.
Consequences of Complying with Policy
We consider that activities consistent with this policy are “authorized” conduct under the Computer Fraud and Abuse Act. If legal action is initiated by a third party against you and you have complied with Synopsys’ Vulnerability Disclosure policy, Synopsys will make it known that your actions were conducted in compliance with this policy.
Synopsys Vulnerability Disclosure Process Overview
The Synopsys Vulnerability Disclosure Process is executed by the Product Security Incident Response Team (PSIRT). The Synopsys process is based on well-known industry standards, such as NIST-SP-800-61, ISO 29147, and ISO 30111.
The Synopsys PSIRT coordinates the response and, if necessary, disclosure of security incidents related to Synopsys products and associated software. Synopsys PSIRT's primary objective is to minimize the risks associated with security incidents in a timely, secure, and responsible manner.
Synopsys will investigate all reports for Synopsys products/platforms that are currently supported; accepted reports will be prioritized based on severity and other environmental factors.
Throughout this process, Synopsys will strive to work collaboratively with the reporting party to validate and collect additional information as necessary. Upon determining the validity of a reported vulnerability, Synopsys will share results with the reporting party, to the extent it may do so without risk to end users. These results, depending on the security issue, include whether the report has been accepted or rejected, severity, timelines, resolution, and public disclosure plans. If the reporting party does not agree with the shared results, Synopsys will make good faith efforts to address the concerns.
During this process, Synopsys will manage all information regarding a reported vulnerability on a confidential basis. Internal distribution is limited to those individuals who have a legitimate need to know and can actively assist in the resolution. Synopsys, similarly, requires the reporting party to maintain strict confidentiality until the reported vulnerability has been comprehensively remediated.
Although this policy addresses disclosure of vulnerabilities in our products, in the event that a reported vulnerability involves a vendor product, Synopsys will notify the vendor directly, coordinate with the incident reporter, or engage a third-party coordination center.
Additionally, if Synopsys becomes aware of a vulnerability that does not affect our products/platforms, Synopsys will follow our policy for reporting vulnerabilities to vendors.
Assessing Vulnerability Severity
Synopsys encourages individuals who report vulnerabilities to evaluate and assign an initial severity using an industry-recognized standard, such as CVSSv3, NIST 800-30 rev1, SSVC, etc. While in the “Analysis” phase, Synopsys will take into consideration the reported severity while formulating an official severity. The official severity will be created using CVSSv3 (or another industry recognized standard) and, whenever possible, used with other environmental factors to prioritize remediation/disclosure timelines.
Given the complexity of security issues in the hardware context this can lead to longer embargo periods than the software industry standard of 90 days. This time can be necessary for Synopsys’ customers to devise and implement mitigation strategies. In the event that Synopsys believes it will take longer than 90 days to release a fix, Synopsys will inform the reporting party of this and the extenuating circumstances which necessitate an extended embargo period.
Acknowledgement and Publication
Synopsys values the efforts of external security researchers, industry organizations, vendors, customers, and other sources who identify security vulnerabilities and responsibly disclose them to Synopsys so that fixes can be issued to all customers. While Synopsys will not pay bounties or other monetary compensation for reporting vulnerabilities in our products, Synopsys’ policy is to acknowledge all researchers in the product/platform release notes and/or public disclosures, provided the following conditions are met:
- The reporting party agrees to their name, handle, or other contact details being shared publicly
- The reporting party does not publish the vulnerability prior to Synopsys confirming a comprehensive fix has been released
- The reporting party does not divulge exact details of the issue, for example, exploits or proof-of-concept code
Note: Synopsys does not publicly acknowledge Synopsys employees or contractors of Synopsys and its subsidiaries for vulnerabilities found in Synopsys products/platforms.
About CVSS
FIRST.Org, Inc (FIRST) is a non-profit organization based out of the US that owns and manages CVSS. It is not required to be a member of FIRST to utilize or implement CVSS but FIRST does require any individual or organization give appropriate attribution while using CVSS. FIRST also states that any individual or organization that publishes scores follow the guideline so that anyone can understand how the score was calculated.
