Exploitability
| CWE ID | Description |
|---|---|
| CWE-696 | The product performs multiple related behaviors, but the behaviors are performed in the wrong order in ways that may produce resultant weaknesses. |
| 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. |

Can you explain this vulnerability to me?
This vulnerability is an integer overflow in Little CMS (lcms2) versions through 2.18. It occurs in the CubeSize function within the cmslut.c file because the check for overflow happens after a multiplication operation, which allows the overflow to occur.
How can this vulnerability impact me? :
The vulnerability has a CVSS base score of 4.0, indicating a low severity impact. It requires local access (AV:L) with high attack complexity (AC:H), no privileges (PR:N), and no user interaction (UI:N). The impact is limited to low confidentiality impact (C:L) and low availability impact (A:L), with no integrity impact (I:N). This means an attacker with local access might cause some limited information disclosure or availability issues.
