Amazon Linux AMI : ImageMagick (ALAS-2021-1479)

high Nessus Plugin ID 146570

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of ImageMagick installed on the remote host is prior to 6.9.10.68-3.23. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1479 advisory.

- ImageMagick before 6.9.11-40 and 7.x before 7.0.10-40 mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c.
(CVE-2020-29599)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update ImageMagick' to update your system.
