CVE-2026-21495 is identified as a medium-severity vulnerability affecting the iccDEV software. This vulnerability allows for a division by zero in the TIFF Image Reader, which can lead to high availability impact. Organizations using versions prior to 2.3.1.2 are particularly at risk. As such, organizations should prioritize patching immediately to mitigate potential disruptions.
The vulnerability has been assigned a CVSS score of 5.5, indicating medium severity. This assessment highlights the necessity for organizations to address this vulnerability promptly, as failure to do so could result in system instability and service interruptions.
Exploitability of this vulnerability is categorized as medium, with the requirement for user interaction. While there is no known public exploit or proof of concept, the division by zero issue is a critical concern that needs to be addressed to prevent potential exploitation.
Affected organizations should take immediate action to upgrade to version 2.3.1.2 or later to ensure their systems are protected against this vulnerability.
Vulnerability Details
According to the CVE description, iccDEV provides a set of libraries and tools for the interaction and manipulation of ICC color management profiles. The vulnerability specifically occurs in the TIFF Image Reader component of iccDEV, which has been patched in version 2.3.1.2. Affected users are strongly advised to upgrade as soon as possible.
Technical Analysis
This vulnerability originates from improper handling of certain inputs in the TIFF Image Reader, which can lead to a division by zero condition. The attack vector is local, meaning that an attacker must have access to the local system to exploit this vulnerability. With low attack complexity and no privileges required, the potential risk increases significantly if user interaction is involved.
The implications of this vulnerability primarily affect the availability of the system rather than confidentiality or integrity. Therefore, organizations must assess their risk posture and implement necessary mitigations.
Risk & Impact Analysis
Risk to organizations includes potential downtime and service disruption due to the availability impact associated with this vulnerability. Given that this vulnerability requires user interaction, the likelihood of a successful exploit may vary depending on the environment and user behavior. Organizations should assess their current risk level and act accordingly.
Exploitation Status
Signal | Status |
|---|---|
