Description Pedro Sampaio 2017-08-30 14:09:50 UTC

In ImageMagick 7.0.6-8, the WritePDFImage function in coders/pdf.c
operates on an incorrect data structure in the "dump uncompressed
PseudoColor packets" step, which allows attackers to cause a denial of
service (assertion failure in WriteBlobStream in MagickCore/blob.c) via
a crafted file.
