CVE-2026-71202 (GCVE-0-2026-71202)

Vulnerability from cvelistv5 – Published: 2026-08-05 06:58 – Updated: 2026-08-10 11:44

Title

raster - Integer Underflow in crop() Offset Handling Causes Capacity-Overflow Panic

Summary

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.

Severity

7.5 (High)

Vulnerability from github – Published: 2026-08-05 09:31 – Updated: 2026-08-05 09:31

Details

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.

Severity

7.5 (High)
