For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Avoid using the `tiffcrop` utility to process TIFF image files from untrusted sources. If the `libtiff-tools` package, which provides `tiffcrop`, is not required, consider removing it to prevent exploitation.
