Technical details

An out-of-bounds (OOB) write vulnerability (CWE-787) exists in the ImageMagick ICON decoder. The flaw is caused by an incorrect loop implementation during the decoding process, which allows data to be written past the boundaries of the allocated heap buffer. An attacker can exploit this by providing a maliciously crafted ICON file, potentially delivered over a network if the application processes external images. Successful exploitation results in a memory corruption that triggers an application crash (Denial of Service). The vulnerability is addressed in Magick.NET version 14.14.0.
