DescriptionGitHub Advisory

iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Versions prior to 2.3.1.2 have an undefined behavior issue when floating-point NaN values are converted to unsigned short integer types during ICC profile XML parsing potentially corrupting memory structures and enabling arbitrary code execution. This vulnerability affects users of the iccDEV library who process ICC color profiles. ICC Profile Injection vulnerabilities arise when user-controllable input is incorporated into ICC profile data or other structured binary blobs in an unsafe manner. Version 2.3.1.2 contains a fix for the issue. No known workarounds are available.

AnalysisAI

Arbitrary code execution in iccDEV versions before 2.3.1.2 occurs when malformed ICC color profiles containing NaN floating-point values are parsed, causing undefined behavior during type conversion that corrupts memory structures. Local attackers can exploit this by crafting malicious ICC profiles that applications process, and public exploit code exists for this vulnerability. …
