Summaryinfo

A vulnerability identified as problematic has been detected in kosinix raster up to 0.2.1. This issue affects the function crop of the file src/editor.rs of the component Crop Handler. Performing a manipulation of the argument offset_x/offset_y results in integer overflow. This vulnerability is known as CVE-2026-71202. Remote exploitation of the attack is possible. No exploit is available.

Detailsinfo

A vulnerability was found in kosinix raster up to 0.2.1. It has been classified as problematic. This affects the function crop of the file src/editor.rs of the component Crop Handler. The manipulation of the argument offset_x/offset_y with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as 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 can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on availability. The summary by CVE is:

The raster Rust crate's crop() function (src/editor.rs) clamps the crop width/height against source dimensions but only clamps the offset_x/offset_y parameters against 0, never against the source width/height. When an offset exceeds the corresponding source dimension, `width2 - offset_x` (or the height equivalent) underflows to a negative i32, which release builds do not trap; the negative value is then cast to usize inside Image::blank()'s Vec::with_capacity() call, triggering a capacity-overflow panic and crashing the process on a single crafted crop request.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-71202 since 08/05/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/05/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
