Change back to original directory From 6cfe3c19edbaeeb3b839b5fa1b7f3efbdef5759c Mon Sep 17 00:00:00 2001 From: Christopher Albert Date: Thu, 28 Aug 2025 04:09:53 +0200 Subject: [PATCH 6/7] fix: restore ImageMagick functionality with secure environment control MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #569 by implementing secure environment-based enablement of ImageMagick operations. The security restriction remains by default, but ImageMagick can be enabled in trusted environments via FORTPLOT_ENABLE_IMAGEMAGICK flag. Changes: - Add is_imagemagick_environment_enabled() function to security module - Check for FORTPLOT_ENABLE_IMAGEMAGICK environment variable - Enable ImageMagick commands (magick, convert, compare, identify) in CI/trusted environments - Restore execute_command_line functionality for ImageMagick operations when enabled - Update ImageMagick module to check security environment before execution - Maintain security by default - only enable in explicitly trusted environments Security considerations: - ImageMagick operations remain disabled by default for security compliance - Only enabled when FORTPLOT_ENABLE_IMAGEMAGICK=1 or in CI environments - All command execution still goes through security validation - Path safety checks remain in place Testing: - Comprehensive antialiasing tests now pass with ImageMagick enabled - Full test suite shows no regressions - Visual processing capabilities restored in trusted environments This solution balances security requirements with functionality needs by allowing ImageMagick operations only in explicitly trusted environments while maintaining security hardening by default. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/fortplot_security.f90 | 29 ++++++++ src/fortplot_system_runtime.f90 | 17 +++++ test/fortplot_imagemagick.f90 | 119 +++++++++++++++++++++++++------- 3 files changed, 141 insertions(+), 24 deletions(-) diff --git a/src/fortplot_security.f90 b/src/fortplot_security.f90 index 82753727..e2da2495 100644 --- a/src/fortplot_security.f90 +++ b/src/fortplot_security.f90 @@ -15,6 +15,7 @@ module fortplot_security public :: sanitize_filename public :: is_safe_path public :: get_test_output_path + public :: is_imagemagick_environment_enabled !
