Exploitability
| 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. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an integer overflow or wraparound issue in the RawTherapee software, specifically in the rtengine modules and associated with the program file dcraw.cc. It occurs in the function parse_qt(), where an integer overflow can happen, potentially leading to unexpected behavior or security risks during image processing. [1]
How can this vulnerability impact me? :
The integer overflow vulnerability could be exploited to cause incorrect processing of image data, which might lead to crashes, memory corruption, or other unintended behavior. This can potentially be leveraged by an attacker to execute arbitrary code or cause denial of service when processing maliciously crafted images. [1]
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, update RawTherapee to a version that includes the security fix committed on April 22, 2025, which addresses the integer overflow in the parse_qt() function within dcraw.cc. Applying this patch prevents potential exploitation of the integer overflow vulnerability. [1]
