In ImageMagick before 6.9.9-1 and 7.x before 7.0.6-2, the ReadOnePNGImage function in coders/png.c allows remote attackers to cause a denial of service (application hang in LockSemaphoreInfo) via a PNG file with a width equal to MAGICK_WIDTH_LIMIT.

In ImageMagick before 6.9.9-4 and 7.x before 7.0.6-4, a crafted file could trigger a memory leak in ReadOnePNGImage in coders/png.c.

In ImageMagick before 6.9.9-0 and 7.x before 7.0.6-1, a crafted PNG file could trigger a crash because there was an insufficient check for short files.

In ImageMagick before 6.9.9-0 and 7.x before 7.0.6-1, the ReadOneMNGImage function in coders/png.c has an out-of-bounds read with the MNG CLIP chunk.

The WriteBlob function in MagickCore/blob.c in ImageMagick before 6.9.8-10 and 7.x before 7.6.0-0 allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted file.

The ReadCINImage function in coders/cin.c in ImageMagick before 6.9.9-0 and 7.x before 7.0.6-1 allows remote attackers to cause a denial of service (memory consumption) via a crafted file.

The WriteOnePNGImage function in coders/png.c in ImageMagick through 6.9.9-0 and 7.x through 7.0.6-1 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted file.

The ReadTXTImage function in coders/txt.c in ImageMagick through 6.9.9-0 and 7.x through 7.0.6-1 allows remote attackers to cause a denial of service (infinite loop) via a crafted file, because the end-of-file condition is not considered.

The ReadOneJNGImage function in coders/png.c in ImageMagick through 6.9.9-0 and 7.x through 7.0.6-1 allows remote attackers to cause a denial of service (large loop and CPU consumption) via a malformed JNG file.

The ReadOneDJVUImage function in coders/djvu.c in ImageMagick through 6.9.9-0 and 7.x through 7.0.6-1 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a malformed DJVU image.
