Description Thomas Deutschmann gentoo-dev 2017-03-02 00:22:07 UTC
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. Please see bug 611356 for details.
Comment 1 Thomas Deutschmann gentoo-dev 2017-03-02 00:26:32 UTC
Probably only affected when "tiff" USE flag is set which isn't the default.
