urlize and urlizetrunc were subject to a potential denial of service attack
via certain inputs with a very large number of brackets.

Notes

Author	Note
alexmurray	upstream advises that only versions 4.2, 5.0 and 5.1 (plus main development branch) are affected but it is likely earlier versions may also be affected but upstream do not mention this as they are no longer maintained by them
