Revision 582d188e6e3487180891f1fc457a80dec8be26a8 authored by Christian Heimes on 24 September 2018, 12:38:31 UTC, committed by Miss Islington (bot) on 24 September 2018, 12:38:31 UTC
The SAX parser no longer processes general external entities by default to increase security. Before, the parser created network connections to fetch remote files or loaded local files from the file system for DTD and entities.

(cherry picked from commit 17b1d5d4e36aa57a9b25a0e694affbd1ee637e45) Co-authored-by: Christian Heimes <christian@python.org> https://bugs.python.org/issue17239
