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 a stack overflow (SO) in SIccCalcOp::ArgsUsed(). The issue is observable under AddressSanitizer as a stack-overflow when iccApplyProfiles processes a malicious profile, with the crash occurring while computing argument usage during calculator underflow/overflow checks. This issue has been patched in version 2.3.1.6.
