Description Thomas Deutschmann gentoo-dev 2017-03-02 00:18:50 UTC
ImageMagick and GraphicsMagick encounter a read beyond an allocated heap buffer when reading CMYKA TIFF files which claim to offer fewer samples per pixel than required. A maliciously crafted file could cause the application to crash.
