Hashing of the call graph signatures is completed at the client system. The call graph shows the fully qualified public method names as well as the line number where the function was called.Īlong with creating BOM files, Synopsys Detect creates a file which will be used by the Black Duck KnowledgeBase for matching call graph signatures against BDSA-provided function signatures.

When the property in Synopsys Detect to set to true, Synopsys Detect creates a call graph (a list of calls made by your code) to understand the public methods your code is using in your application. The process to display the possible impact of a vulnerability in Black Duck is: 1. However, that does not indicate that your code is safe from the vulnerability as Synopsys may not have data for a specific vulnerability. Likewise, Black Duck may not denote that a vulnerability is reachable. It is not a definitive list of the vulnerabilities that do or do not affect your code.Īlthough Black Duck may indicate that a vulnerability is reachable, it does not indicate that the vulnerability definitely affects your code, as your code may not trigger the vulnerability. Important: Vulnerability impact analysis can help you triage vulnerabilities in open source components. Using this data, Black Duck can determine if vulnerable code is more likely to be invoked, and flags those vulnerabilities as reachable, indicating to you that these vulnerabilities are a higher priority for remediation. Vulnerability metadata has been added to BDSAs that includes the fully qualified public function names that expose the vulnerability. Vulnerability impact analysis works with Black Duck Security Advisories (BDSAs), a Black Duck-exclusive vulnerability data feed. By knowing whether any external public methods called by your Java applications are potentially involved in a known vulnerability, you can prioritize what vulnerabilities you need to concentrate on.
Black Duck can identify the called fully qualified public functional names in your source code and match them to the known function names being exploited by a vulnerability. To help you to prioritize which vulnerabilities you should address first, Black Duck can determine if any external public methods called by your Java applications are potentially involved in a known vulnerability. If a project version has several vulnerabilities, how can you decide which vulnerability you should focus on first?
