An issue was discovered in Qt before 5.11.3. A malformed GIF image causes a NULL pointer dereference in QGifHandler resulting in a segmentation fault.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
