Summary
ImageMagick Has Signed Integer Overflow in SIXEL Decoder, Leading to Memory Corruption
Details

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.
