Description

CairoSVG security advisories:

When processing SVG files, the python package CairoSVG uses two regular

expressions which are vulnerable to Regular Expression Denial of Service

(REDoS).

If an attacker provides a malicious SVG, it can make cairosvg get stuck

processing the file for a very long time.

Solution(s)

  • freebsd-upgrade-package-py36-cairosvg
  • freebsd-upgrade-package-py37-cairosvg
  • freebsd-upgrade-package-py38-cairosvg
  • freebsd-upgrade-package-py39-cairosvg
