Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the XWD decoder when there is a type confusion between bits_per_pixel and pixmap_depth during the byte-swap process. An attacker can achieve arbitrary code execution or cause a denial of service by providing a crafted XWD image file that triggers out-of-bounds memory access.
