iccDEV, a library for ICC color management profiles, is affected by a NULL pointer dereference vulnerability in versions prior to 2.3.1.2. This vulnerability allows for potential disruptions in service availability. It is classified as a medium severity issue with a CVSS score of 5.5. Organizations utilizing this software need to be aware of the risks associated with this vulnerability and prioritize patching to the latest version.
The vulnerability is due to improper handling of XML data, which could lead to application crashes or degraded performance. The exploitation of this vulnerability requires local access and user interaction, which heightens the risk of availability impacts. Given its potential consequences, timely remediation is crucial.
Organizations should prioritize patching immediately to prevent any disruptions that may arise from exploiting this vulnerability. The patched version 2.3.1.2 addresses this issue, and users are strongly encouraged to upgrade as soon as possible.
As of now, there are no known exploits in the wild, but the nature of the vulnerability warrants attention to ensure that systems remain secure.
Vulnerability Details
The official description states: 'iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, iccDEV is vulnerable to NULL pointer dereference via the XML calculator parser. This issue has been patched in version 2.3.1.2.'
The vulnerability is classified under multiple CWEs, including CWE-20 (Improper Input Validation), CWE-252 (Unchecked Return Value), CWE-476 (NULL Pointer Dereference), and CWE-690 (Unchecked Return Value).
The CVSS version 3.1 score is 5.5, indicating a medium severity level. The attack vector is local, requiring low complexity and no privileges, but user interaction is necessary.
The vulnerability's impact on availability is classified as high, while confidentiality and integrity impacts are noted as none.
Technical Analysis
The root cause of this vulnerability lies in the handling of XML data within the iccDEV application. When the XML calculator parser processes data, it does not adequately check for null values, leading to a potential dereference of a null pointer. This oversight can allow attackers to disrupt the application, causing it to crash or behave unexpectedly.
The attack vector is local, meaning an attacker must have access to the system where iccDEV is running. The attack complexity is low, and no specific privileges are required to exploit this vulnerability, but user interaction is necessary to trigger the exploit.
Given that there is no confidentiality or integrity impact associated with this vulnerability, the primary concern is its effect on availability. Organizations must monitor their systems and ensure that the patched version is implemented to avoid any disruptions.
Risk & Impact Analysis
Risk to organizations includes potential service outages and application crashes due to the exploitation of this vulnerability. With the availability impact rated as high, organizations that rely on iccDEV for color management may face significant disruptions.
The urgency for remediation is moderate due to the lack of known active exploitation in the wild; however, organizations should still address this vulnerability in their patch cycle to mitigate risks.
Given the nature of this vulnerability, organizations that handle sensitive color management tasks should prioritize the application of the patch to ensure uninterrupted service.
