A heap-based buffer overflow was found in GIMP’s Hot color filter plug-in. For very large images, a pixel buffer is allocated using overflowing 32-bit width * height (and related) arithmetic while the filter’s pixel access path uses the true image size, after integer overflow in the allocation size

A heap-based buffer overflow was found in GIMP’s raw data export plug-in. When exporting very large images, g_malloc() sizing based on overflowing width * height * bytes-per-pixel can allocate far less memory than GEGL reads or writes during export, following integer overflow

A heap-based buffer overflow was found in GIMP’s PCX export plug-in. For images with extremely large width and height, buffer allocation uses overflowing 32-bit width * height arithmetic while subsequent GEGL operations use the full extent, after integer overflow in size calculation

A heap-based buffer overflow was found in GIMP’s DICOM export plug-in. When exporting an image with extremely large width and height, the export path allocates a buffer using a 32-bit width * height (and bytes-per-pixel) product that can overflow. GEGL then writes the full uncompressed extent into the undersized buffer, after integer overflow in the allocation size
