This commit modifies cve.py, as well as its users cve-checker and pkg-stats to support CPE ID based matching, for packages that have CPE ID information. One of the non-trivial thing is that we can't simply iterate over all CVEs, and then iterate over all our packages to see which packages have CPE ID information that match the CPEs affected by the CVE. Indeed, this is an O(n^2) operation. So instead, we do a pre-filtering of packages potentially affected. In check_package_cves(), we build a cpe_product_pkgs dict that associates a CPE product name to the packages that have this CPE product name. The CPE product name is either derived from the CPE information provided by the package if available, and otherwise we use the package name, which is what was used prior to this patch. And then, when we look at CVEs, we only consider the packages that have a CPE product name matching the CPE products affected by the CVEs. This is done in check_package_cve_affects().

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
