be published soon.

Bug description:
  [Impact]

  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.

  [Test Plan]

  1. Install libqt5svg5-dev, qtbase5-dev and their dependencies.
  2. Build the attached project with the system's version of Qt:
     /usr/lib/qt5/bin/qmake test-2021-38593.pro && make
  3. Start the resulting binary and pass the path to the included input file as 
first parameter:
     ./test-2021-38593 ./input.svg
     The binary should return immediately and without error messages. If it 
doesn't, you might be affected.

  [Where problems could occur]

  The fix tries to skip drawing dashes that would be invisible anyway.
  So a potential problem may that it skips too much. In fact, this has
  already happened, and upstream had to adjust the fix.

  [Other Info]
