## **Vulnerability Details** When performing image magnification in `ReadOneMNGIMage` (in `coders/png.c`), there is an issue around the handling of images with separate alpha channels. When loading an image with a color type that implies a separate alpha channel (ie. `jng_color_type >= 12`), we will load the alpha pixels in this loop: ```c if (logging != MagickFalse) (void) LogMagickEvent(CoderEvent,GetMagickModule(), " Reading alpha from alpha_blob."); jng_image=ReadImage(alpha_image_info,exception); if (jng_image != (Image *) NULL) for (y=0; y < (ssize_t) image->rows; y++) { s=GetVirtualPixels(jng_image,0,y,image->columns,1,exception); q=GetAuthenticPixels(image,0,y,image->columns,1,exception); // [0] if ((s == (const Quantum *) NULL) || (q == (Quantum *) NULL)) break; if (image->alpha_trait != UndefinedPixelTrait) for (x=(ssize_t) image->columns; x != 0; x--) ...

A 22-year-old Oregon man has been arrested on suspicion of operating "Rapper Bot," a massive botnet used to power a service for launching distributed denial-of-service (DDoS) attacks against targets -- including a March 2025 DDoS that knocked Twitter/X offline. The Justice Department asserts the suspect and an unidentified co-conspirator rented out the botnet to online extortionists, and tried to stay off the radar of law enforcement by ensuring that their botnet was never pointed at KrebsOnSecurity.
