description

image_optimizer 1.3.0 through 1.9.0 can execute operating-system commands while determining an image format. An attacker needs control of an image path, such as an uploaded filename, and the identify option must be enabled.

mitigation

Disable the identify option where possible. Restrict image paths and filenames to trusted, validated values until a fixed release is available.

outcome

Mechanism verified: the exploit fired on the vulnerable build and stayed silent on the patched one, but the server it ran against was ours, so no check ships for it.
