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

Details

imagecli's scale <ratio> pipeline operation (Scale::apply() in src/image_ops.rs) computes output width/height as (dimension as f32 * ratio) as u32 with no upper-bound validation on the CLI-supplied ratio, which is parsed via nom::number::complete::float with no range check. A large ratio (e.g. 100000) causes an attempted allocation of hundreds of terabytes, aborting the process. Any application embedding imagecli as a library and accepting user-controlled pipeline strings is remotely crashable with a single request.

Severity

7.5 (High)

Title

imagecli - Uncontrolled Memory Allocation via Unbounded scale Ratio Causes Denial of Service

Summary

imagecli's pipeline operation (Scale::apply in src/image_ops.rs) computes output width/height as (dimension as f32 * ratio) as u32 with no upper-bound validation on the CLI-supplied ratio, which is parsed via nom::number::complete::float with no range check. Any application embedding imagecli as a library and accepting user-controlled pipeline strings is remotely crashable with a single request.
