Vulnerability details
The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.
The weakness exists in the ppm_load_read_header function as defined in the operations/external/ppm-load.c source code file due to improper restrictions of memory allocation. A remote attacker can trick the victim into opening a specially crafted PPM file, trigger out-of-bounds write in the gegl_buffer_iterate_read_simplefunction in the buffer/gegl-buffer-access.c source code file and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
