Information Disclosure

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 CIccCalculatorFunc::ApplySequence() due to invalid enum values being loaded for icChannelFuncSignature. The issue is observable under UBSan as a “load of value … not a valid value for type icChannelFuncSignature”, indicating a type/enum value confusion scenario during ICC profile processing. This issue has been patched in version 2.3.1.6.

Analysis

Undefined Behavior in iccDEV prior to version 2.3.1.6 allows local attackers to cause a denial of service by supplying a crafted ICC color profile containing invalid enum values for icChannelFuncSignature, which triggers an application crash during profile processing in CIccCalculatorFunc::ApplySequence(). The vulnerability requires local file access or the ability to provide a malicious ICC profile to an application using the library; no public exploit code has been identified.
