Buffer overflow in the xcf_load_vector function in app/xcf/xcf-load.c for gimp before 2.2.12 allows user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via an XCF file with a large num_axes value in the VECTORS property.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
