This update for python-CairoSVG, python-Pillow fixes the following issues:

Update to version 2.5.1.

• Security fix: When processing SVG files, CairoSVG was using two regular expressions which are vulnerable to Regular Expression Denial of Service (REDoS). If an attacker provided a malicious SVG, it could make CairoSVG get stuck processing the file for a very long time.
• Fix marker positions for unclosed paths
• Follow hint when only output_width or output_height is set
• Handle opacity on raster images
• Don’t crash when use tags reference unknown tags
• Take care of the next letter when A/a is replaced by l
• Fix misalignment in node.vertices

Updates for version 2.5.0.

• Drop support of Python 3.5, add support of Python 3.9.
• Add EPS export
• Add background-color, negate-colors, and invert-images options
• Improve support for font weights
• Fix opacity of patterns and gradients
• Support auto-start-reverse value for orient
• Draw images contained in defs
• Add Exif transposition support
• Handle dominant-baseline
• Support transform-origin
