A flaw was found in GIMP's PSD parser. An integer overflow in read_RLE_channel() can cause an undersized heap allocation for the RLE row-length table, after which subsequent per-row writes corrupt heap memory. This could lead to memory corruption, potentially resulting in denial of service or arbitrary code execution.
