ImageMagick's Security Policy Bypass through config/policy-secure.xml via "fd handler" leads to stdin/stdout access
Résumé
ImageMagick's Security Policy Bypass through config/policy-secure.xml via "fd handler" leads to stdin/stdout access
Description d'origine
La description telle que publiée par la source (souvent en anglais).
ImageMagick is free and open-source software used for editing and manipulating digital images. The shipped "secure" security policy includes a rule intended to prevent reading/writing from standard streams. However, ImageMagick also supports fd: pseudo-filenames (e.g., fd:0, fd:1). Prior to versions 7.1.2-15 and 6.9.13-40, this path form is not blocked by the secure policy templates, and therefore bypasses the protection goal of "no stdin/stdout." Versions 7.1.2-15 and 6.9.13-40 contain a patch by including a change to the more secure policies by default. As a workaround, add the change to one's security policy manually.
