CVE-2026-71202
raster - Integer Underflow in crop() Offset Handling Causes Capacity-Overflow Panic
Description
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.

Action Type Old Value New Value Changed Translation Title: raster de kosinix, Description: La función ’crop()’ del crate ’raster’ de Rust (src/editor.rs) limita el ancho/alto del recorte con respecto a las dimensiones de origen, pero solo limita los parámetros ’offset_x’/’offset_y’ con respecto a 0, nunca con respecto al ancho/alto de origen. Cuando un desplazamiento excede la dimensión de origen correspondiente, ’width2 - offset_x’ (o el equivalente para la altura) sufre un desbordamiento negativo a un ’i32’ negativo, lo cual las compilaciones de lanzamiento no interceptan; el valor negativo se castea luego a ’usize’ dentro de la llamada a ’Vec::with_capacity()’ de ’Image::blank()’, lo que desencadena un pánico por desbordamiento de capacidad y bloquea el proceso con una única solicitud de recorte manipulada.

Action Type Old Value New Value Changed Description 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.
