CVE-2026-21485 is a high-severity vulnerability that affects the Color iccDEV library, which provides a set of tools for managing ICC color profiles. This vulnerability allows for undefined behavior (UB) and out-of-memory errors in versions 2.3.1.1 and below. The CVSS score for this vulnerability is 8.8, indicating a high level of risk due to its potential impact on confidentiality, integrity, and availability.
The risk to organizations includes the possibility of exploitation that could lead to severe performance issues or system crashes. Attackers may leverage this vulnerability over the network, and while user interaction is required, the attack complexity is considered low, which increases the urgency for remediation. Organizations should prioritize patching immediately.
This vulnerability has been analyzed and a fix is available in version 2.3.1.2. Organizations using affected versions should upgrade to mitigate the risks associated with undefined behavior and potential out-of-memory conditions.
Given the high severity rating and potential for exploitation, it is crucial for affected organizations to take immediate action to apply the necessary patches and ensure their systems are secure.
Vulnerability Details
The official description of CVE-2026-21485 states that the Color iccDEV library, which supports ICC color management profiles, is subject to undefined behavior and out of memory errors in versions up to 2.3.1.1. The vulnerability has been classified under multiple CWE identifiers, including CWE-20 (Improper Input Validation) and CWE-400 (Uncontrolled Resource Consumption).
The CVSS score of 8.8 indicates a high severity level, with a network attack vector and low complexity. There are no privileges required for exploitation, but user interaction is necessary, emphasizing the need for awareness among users of the affected systems.
Technical Analysis
The root cause of this vulnerability lies in the way the Color iccDEV library handles certain inputs, which can lead to conditions that trigger undefined behavior. The attack vector is network-based, allowing attackers to exploit this vulnerability remotely. The attack complexity is low, which means it does not require sophisticated methods to exploit.
Exploitation of this vulnerability does not require elevated privileges, and user interaction is necessary, which could involve opening specially crafted files or interacting with the application's interface in an unintended manner. The potential impacts include high confidentiality, integrity, and availability effects, which could compromise the overall functionality of the application.
Risk & Impact Analysis
Organizations utilizing the Color iccDEV library face significant risks due to this vulnerability. The potential for undefined behavior and out-of-memory errors can lead to application crashes and service disruptions, impacting business operations. The vulnerability's network attack vector further increases the risk, as attackers can exploit it remotely without needing physical access to the affected systems.
Given the high CVSS score of 8.8, organizations should treat this vulnerability with high urgency. Immediate patching is essential to reduce the risk of exploitation, particularly for those in sectors where availability and data integrity are critical.
