ImageMagick has infinite loop when writing IPTCTEXT leads to denial of service via crafted profile
A crafted profile contain invalid IPTC data may cause an infinite loop when writing it with `IPTCTEXT`.

ImageMagick: Heap Buffer Over-read in WaveletDenoise when processing small images
A heap buffer over-read vulnerability occurs when processing an image with small dimension using the `-wavelet-denoise` operator.

ImageMagick: Heap overflow in sun decoder on 32-bit systems may result in out of bounds write
An Integer Overflow vulnerability exists in the sun decoder. On 32-bit systems/builds, a carefully crafted image can lead to an out of bounds heap write.

ImageMagick Has Signed Integer Overflow in SIXEL Decoder, Leading to Memory Corruption
A signed integer overflow vulnerability in ImageMagick's SIXEL decoder allows an attacker to trigger memory corruption and denial of service when processing a maliciously crafted SIXEL image file. The vulnerability occurs during buffer reallocation operations where pointer arithmetic using signed 32-bit integers overflows.

```

ImageMagick has memory leak in msl encoder
Memory leak exists in `coders/msl.c`. In the `WriteMSLImage` function of the `msl.c` file, resources are allocated. But the function returns early without releasing these allocated resources.
