Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-202101-36 (ImageMagick: Command injection)

A flaw in ImageMagick’s handling of password protected PDFs was discovered. Impact :

A remote attacker could entice a user to open a specially crafted PDF using ImageMagick possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. Workaround :

Do not open untrusted PDFs.
