libqt5svg5 5.12.8-0ubuntu1 in Ubuntu 20.04 is affected by CVE-2021-38593:
https://nvd.nist.gov/vuln/detail/CVE-2021-38593

Trying to open the attached svg file will block one core at 100% and occupy much memory. Depending on the configuration, it might even run out of memory and crash. This is fixed upstream by:
https://codereview.qt-project.org/c/qt/qtbase/+/377942

The original issue is public since July 29th. If I'm allowed to upload further files, I'll send a simple test program.
