   An update that fixes two vulnerabilities is now available.

Description:

   This update for python-CairoSVG fixes the following issues:

   - CVE-2023-27586: Don't allow fetching external files unless explicitly
     asked for.  (boo#1209538)

   - Update to version 2.5.2

     * Fix marker path scale

   - Update to version 2.5.1 (boo#1180648, CVE-2021-21236):

     * 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
