In short

iccDEV color profile software has a critical flaw where a deleted object is still being accessed in memory, allowing attackers to crash the application or potentially execute malicious code. This affects how the software manages color profiles, which are widely used in image processing.

Technical detail

A Use After Free vulnerability exists in iccDEV's CIccXform::Create() function where the hint manager object is improperly deleted but subsequently accessed. An attacker can trigger this by providing a specially crafted ICC color profile file, leading to memory corruption, denial of service, or arbitrary code execution depending on heap layout and exploitation sophistication.
