Detailed vulnerability description
The vulnerability allows a remote unauthenticated attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists due to improper handling of PNG files during a call to the babl_format_get_bytes_per_pixel function in the babl-format.csource code file. A remote attacker can trick the victim into accessing a specially crafted PNG file, trigger out-of-bounds write in the gegl_tile_backend_swap_constructedfunction in the buffer/gegel-tile-backend-swap.c source code file, and cause the service to crash or execute arbitrary code.
