Technical details
The vulnerability exists in the QueueAuthenticPixelCacheNexus function in MagickCore/cache.c, which fails to validate that requested pixel region width and height are non-zero and do not exceed image bounds. An attacker can craft an SVG that repeatedly requests a zero-width or zero-height pixel region, causing an infinite loop. The fix adds validation to reject requests with zero dimensions or out-of-bounds regions.
