CVE-2026-34537 Details
Description
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger Undefined Behavior (UB) in CIccOpDefEnvVar::Exec() due to invalid enum values being loaded for icSigCmmEnvVar. The issue is observable under UBSan as a “load of value … not a valid value for type icSigCmmEnvVar”, indicating an invalid enum/type value being consumed during ICC profile processing. This issue has been patched in version 2.3.1.6.
A vulnerability in iccDEV versions prior to 2.3.1.6 allows a crafted ICC profile to trigger undefined behavior in the function CIccOpDefEnvVar::Exec(). This occurs because invalid enum values are loaded for icSigCmmEnvVar, leading to the consumption of incorrect type values during ICC profile processing. The issue can be detected under Undefined Behavior Sanitizer (UBSan) as a load of an invalid value for the type icSigCmmEnvVar.
Users can update to iccDEV version 2.3.1.6, which addresses the vulnerability by adding validation to prevent undefined behavior when processing ICC profiles. Instructions for updating are available on the iccDEV GitHub repository.
