Exploitability
| CWE ID | Description |
|---|---|
| CWE-681 | When converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting values are used in a sensitive context, then dangerous behaviors may occur. |
| 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-476 | The product dereferences a pointer that it expects to be valid but is NULL. |
| 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?
This vulnerability is a Type Confusion issue in the iccDEV library, specifically in the function SIccCalcOp::ArgsPushed() located in IccProfLib/IccMpeCalc.cpp. It affects versions prior to 2.3.1.2 and allows improper handling of ICC color profiles, potentially leading to unexpected behavior or exploitation.
How can this vulnerability impact me? :
The vulnerability can lead to severe impacts including high confidentiality, integrity, and availability risks, as indicated by its CVSS score of 8.8. Exploitation could allow an attacker to execute arbitrary code, cause crashes, or manipulate color profile data when processing ICC profiles using the iccDEV library.
What immediate steps should I take to mitigate this vulnerability?
Upgrade the iccDEV library to version 2.3.1.2 or later, as this version contains the patch for the Type Confusion vulnerability. No known workarounds are available.
