What the vulnerability does

01Description

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) via a null-pointer member call in CIccCombinedConnectionConditions::CIccCombinedConnectionConditions() (reported by UBSan as “member call on null pointer of type CIccTagSpectralViewingConditions”). The issue is reachable when running iccApplyNamedCmm with -PCC using a malformed .icc profile. This issue has been patched in version 2.3.1.6.
