libX11.so is vulnerable to integer overflow. The vulnerability is due to insufficient validation checks within the XCreateImage function when calculating the image data size. This issue happen during the calculation of min_bytes_per_line, which can potentially return a value that is too small for the actual image data. This flaw allows an attacker to trigger an integer overflow and execute arbitrary code with elevated privileges
