Description Martin Prpič 2016-04-29 07:50:45 EDT

A denial of service flaw was found in the way the librsvg2 library parsed SVG files. A specially crafted SVG file with circular definitions could cause an application using librsvg2 to crash.

This flaw is in the _rsvg_css_normalize_font_size() function.
