Exploitability
| CWE ID | Description |
|---|---|
| CWE-122 | A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). |
| CWE-20 | The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-24406 is a heap buffer overflow vulnerability in the iccDEV library, specifically in the function CIccTagNamedColor2::SetSize(). This vulnerability occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs, leading to improper handling of size fields. The overflow happens because the SetSize() function reads beyond the allocated heap buffer, causing out-of-bounds memory access. This issue arises during parsing of ICC profile XML data, particularly when processing named color tags, and is triggered by malformed or crafted input. The vulnerability affects versions 2.3.1.1 and below and has been fixed in version 2.3.1.2. [2, 3]
How can this vulnerability impact me? :
Exploitation of this vulnerability can allow an attacker to cause a denial of service (DoS) by crashing applications that process ICC profiles. Additionally, it can enable manipulation of ICC tag tables, offsets, or size fields, potentially bypassing application logic that relies on profile metadata. In some cases, it may allow arbitrary code execution if vulnerable native libraries process the malformed ICC profile. The vulnerability has a high severity with impacts on confidentiality, integrity, and availability. [2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by analyzing ICC profile files for malformed or crafted XML input that triggers the heap buffer overflow in the CIccTagNamedColor2::SetSize() function. Detection may involve using AddressSanitizer or similar memory error detection tools during ICC profile parsing to identify out-of-bounds reads or heap-buffer-overflows. Since the issue occurs during XML parsing of ICC profiles, monitoring or scanning ICC profile files for suspicious or malformed named color tags could help. Specific commands are not provided in the resources. [3, 2]
What immediate steps should I take to mitigate this vulnerability?
The immediate mitigation step is to update the iccDEV library to version 2.3.1.2 or later, where the vulnerability has been fixed. No workarounds are provided, so upgrading to the patched version is necessary to prevent exploitation. [2]
