Null Pointer Dereference Denial Of Service

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) 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.

Analysis

Denial of service in iccDEV prior to version 2.3.1.6 allows local attackers to crash the iccApplyNamedCmm tool by supplying a malformed ICC color profile that triggers a null-pointer dereference in the CIccCombinedConnectionConditions constructor. The vulnerability requires local file system access to provide the crafted profile and causes application termination with no code execution or data corruption, affecting users processing untrusted ICC profiles through the -PCC flag.
