NVD Description
Note: Versions mentioned in the description apply only to the upstream flatpak-builder package and not the flatpak-builder package as distributed by RHEL.
Flatpak is a Linux application sandboxing and distribution framework. Prior to 1.16.4, the caching for ld.so removes outdated cache files without properly checking that the app controlled path to the outdated cache is in the cache directory. This allows Flatpak apps to delete arbitrary files on the host. This vulnerability is fixed in 1.16.4.
