For an application that originates from an OS package, the vulnerability data for CVEs is sourced from the relevant feed for the OS package. In some cases, like with Amazon Linux and Photon OS, this CVE information is provided in security advisories such as Amazon Linux Security Advisories (ALAS) for Amazon, and PHSA for Photon. In such cases, the correlation for the relevant vulnerabilities is limited.
As an example, when the application “python” is sourced from an Amazon Python package, CVEs found for the python application (as a binary) will not be correlated with the relevant Amazon CVEs from the ALAS.
