Description Vladimir Vasilev 2026-08-25 07:01:12 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

An integer overflow in the libtiff rgb2ycbcr utility's cvtRaster() function when computing strip buffer sizes can result in an undersized heap allocation and subsequent heap-based buffer overflow during YCbCr conversion of a crafted TIFF image
