ImageMagick: Integer overflow in DIB coder can result in out of bounds read or write
An integer overflow in DIB coder can result in out of bounds read or write

ImageMagick has heap buffer overflow in WriteXWDImage due to CARD32 arithmetic overflow in bytes_per_line calculation
A 32-bit unsigned integer overflow in the XWD (X Windows) encoder can cause an undersized heap buffer allocation. When writing a extremely large image an out of bounds heap write can occur.

ImageMagick has Heap Buffer Over-Read in BilateralBlurImage
BilateralBlurImage contains a heap buffer over-read caused by an incorrect conversion. When processing a crafted image with the `-bilateral-blur` operation an out of bounds read can occur.

ImageMagick: Write heap-buffer-overflow in PCL encoder via undersized output buffer
A heap-buffer-overflow vulnerability exists in the PCL encode due to an undersized output buffer allocation.

ImageMagick has a Path Policy TOCTOU symlink race bypass
`domain="path"` authorization is checked before final file open/use. A symlink swap between check-time and use-time bypasses policy-denied read/write.

ImageMagick has heap use-after-free in the MSL encoder
A heap-use-after-free vulnerability exists in the MSL encoder, where a cloned image is destroyed twice. The MSL coder does not support writing MSL so the write capability has been removed.

```

ImageMagick has a heap buffer over-read via 32-bit integer overflow in MAT decoder
In MAT decoder uses 32-bit arithmetic due to incorrect parenthesization resulting in a heap over-read.

ImageMagick has heap-based buffer overflow in UHDR encoder
A heap-based buffer overflow in the UHDR encoder can happen due to truncation of a value and it would allow an out of bounds write.

ImageMagick has stack buffer overflow in MagnifyImage
MagnifyImage uses a fixed-size stack buffer. When using a specific image it is possible to overflow this buffer and corrupt the stack.

ImageMagick is vulnerable to heap buffer over-write on 32-bit systems in SFW decoder
An overflow on  32-bit systems can cause a crash in the SFW decoder when processing extremely large images.

ImageMagick is vulnerable to Heap Overflow when writing extremely large image profile in the PNG encoder
An extremely large image profile could result in a heap overflow when encoding a PNG image.
