CVE-2022-34526: tiffsplit and tiffcrop can crash when processing malicious TIFF files

CVE-2022-34526 · published 4 years ago

Summary

The tiffsplit and tiffcrop programs that rely on the libtiff library can stop working if they open a specially crafted TIFF image. This could cause a denial of service on systems such as Fedora, Debian, and NetApp products that include libtiff. Apply the latest libtiff updates or avoid opening untrusted TIFF files to prevent the issue.

What to do

Update debian tiff to version 4.4.0-4.
