Heap-based Buffer Overflow in iccDEV ICC Profile Parser

Publication date: 2026-08-21

Last updated on: 2026-08-21

Assigner: GitHub, Inc.

Description
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.

Exploitability

CWE

KEV Icon
CWE ID Description
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
CWE-125 The product reads data past the end, or before the beginning, of the intended buffer.
CWE-704 The product does not correctly convert an object, resource, or structure from one type to a different type.

Executive Summary

CVE-2026-50278 is a size_t underflow vulnerability in the iccDEV library affecting versions before 2.3.2.1. It occurs in the CIccEmbedIO::Read8() function when parsing ICC profiles with specific embedded data tags. This causes an out-of-bounds read that may lead to denial of service.

Detection Guidance

To detect this vulnerability, check the version of iccDEV installed on your system. If it is prior to 2.3.2.1, the system is vulnerable. Use commands like 'find / -name "iccDEV*" -type d' to locate the library or check package managers for installed versions.

Impact Analysis

The vulnerability could allow attackers to cause a denial of service by exploiting the size_t underflow in the library. This might crash applications using affected versions of iccDEV when processing malicious ICC profiles.

Compliance Impact

The provided CVE data does not specify direct impacts on compliance with GDPR, HIPAA, or other standards. The vulnerability primarily causes denial of service via out-of-bounds read, which may disrupt systems but lacks explicit compliance implications in the given context.

Mitigation Strategies

Immediately update iccDEV to version 2.3.2.1 or later. No workarounds are available, so updating is the only mitigation. Verify the update by checking the library version again.
