EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Versions prior to 2.3.2.1 have a CIccEmbedIO::Read8() size_t underflow. The issue arises due to an embedded-profile read defect when parsing ICC profiles containing icSigEmbeddedV5ProfileTag data with icSigEmbeddedProfileType payloads. Version 2.3.2.1 patches the issue. No known workarounds are available.
