CWE ID Description
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.

Executive Summary

This vulnerability is an Integer Overflow or Wraparound issue found in the artraweditor ART software, specifically in the rtengine modules and the program file dcraw.c. It occurs because the ART project copied code from the LibRaw library but did not apply a security patch that fixed a similar vulnerability (CVE-2018-5815) in LibRaw. The flaw allows integer values to overflow or wrap around, which can lead to unexpected behavior or potential security risks.

The vulnerability affects ART versions before 1.25.12 and is related to how the software processes user-supplied input locally.

Impact Analysis

This vulnerability can lead to security issues due to integer overflow or wraparound in the ART software when processing user-supplied input. Although ART is not considered a security-critical application since it processes input locally, the flaw could potentially be exploited to cause unexpected behavior, crashes, or other unintended effects within the application.

Mitigation Strategies

To mitigate this vulnerability, you should update ART to version 1.25.12 or later where the patch addressing the integer overflow in rtengine/dcraw.c has been applied.

The fix involves applying the same security patch that was used in the LibRaw library to eliminate the vulnerability. This patch corrects the integer overflow or wraparound issue in the affected code.

Since ART processes user-supplied input locally and is not considered security-critical, ensuring you have the updated version with the patch is the primary recommended step.
