Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2021-01-06 20:23:24 UTC 
CVE-2021-21236 (https://github.com/Kozea/CairoSVG/commit/cfc9175e590531d90384aa88845052de53d94bf3):

CairoSVG is a Python (pypi) package. CairoSVG is an SVG converter based on Cairo. In CairoSVG before version 2.5.1, there is a regular expression denial of service (REDoS) vulnerability. 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. This is fixed in version 2.5.1. See Referenced GitHub advisory for more information.


Please bump, thanks!
