OS Command Injection in MiniMagick
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| RubyGems | mini_magick | < 4.9.4 | 4.9.4 |
Details
As written in the advisory (Markdown source, shown as plain text).
In `lib/mini_magick/image.rb` in MiniMagick before 4.9.4, a fetched remote image filename could cause remote command execution because `Image.open` input is directly passed to `Kernel#open`, which accepts a `|` character followed by a command.
