description

ImageMagick is affected when processing a crafted image that uses bzip2 compression. An attacker may trigger a stack buffer overwrite if they can cause a vulnerable installation to process such an image.

mitigation

Upgrade ImageMagick to 7.1.2-33 or later, or 6.9.13-58 or later. Until upgraded, restrict processing of untrusted images, particularly inputs using bzip2 compression.

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.
