In these images, version 2.9.1-9.el8 of RedHat package freetype is preinstalled. This package version is vulnerable and has since been patched in 2.9.1-10. 4. During the skia-python Linux build, libfreetype is vendored from the system, resulting in skia-python.libs/libfreetype-29a7443c.so.6.16.1 [ To find the provenance of your vendored libfreetype, we extracted the 8-character hash of the original binary file that is added during the build process (29a7443c), and matched it against our database of hashes all historic Red Hat, Debian and Ubuntu releases of freetype. ] 5.
