Title

imagecli: Negative carve Ratio Bypasses Bounds Check and Crashes Process via Reachable Panic

Summary

imagecli's `carve <ratio>` pipeline operation (Carve::apply() in src/image_ops.rs) only asserts `ratio <= 1.0`, never validating that the ratio is positive. A negative ratio (e.g. -5) causes the computed target width to saturate to 0 via Rust's defined float-to-uint cast, which is then passed to imageproc::seam_carving::shrink_width — a function that panics when given a width below 2, crashing the process. This shares the same missing-input-validation root cause as the sibling `scale` finding in the same file but is an independently fixable, distinct code path.

Severity

7.5 (High)

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

Details

imagecli's carve <ratio> pipeline operation (Carve::apply() in src/image_ops.rs) only asserts ratio <= 1.0, never validating that the ratio is positive. A negative ratio (e.g. -5) causes the computed target width to saturate to 0 via Rust's defined float-to-uint cast, which is then passed to imageproc::seam_carving::shrink_width — a function that panics when given a width below 2, crashing the process. This shares the same missing-input-validation root cause as the sibling scale finding in the same file but is an independently fixable, distinct code path.

Severity
