Bug#947431: xerces-c: CVE-2018-1311: use-after-free vulnerability processing external DTD

[Sylvain Beucler]

Excellent!

I just re-uploaded 3.2.2+debian-1+deb10u1 with the updated patch.
(and tested in a i386 chroot for good measure)

I'm now adapting for stretch-lts (which has a monolithic test result).

Cheers!
