1. Gnumeric has unbalanced XML tags in its doc translations.
2. itstool's XML error handler tries to print this error with context.
3. libxml2's context snipper treats the data as bytes, not UTF-8.
4. python3Packages.libxml2 casts the context to a UTF-8 Python string.
5. itstool dereferences a null pointer.
This patch intervenes at #4.
In https://bugzilla.gnome.org/show_bug.cgi?id=789714#c4 , upstream
suggests that intervening at #3 would be better -- that each of the four
copies of xmlParserPrintFileContextInternal() have four additional UTF-8
problems, one of which is that the caret indicator ought to count
"unicode characters" not bytes. But to position a caret correctly, a
character count is not sufficient -- this would need to use icu's BiDi
logic (with fallback to doing something wrong when libxml2 is configured
not to use icu) -- which makes a 'correct' fix a much larger project
than this simple band-aid.
The static output should only get created when both enableShared and
enableStatic are set. Otherwise there would be libraries missing from
the main output when enableShared = false & enableStatic = true. This
can cause issues in some packages that don’t know about libxml2’s
static output.

This should solve CVE-2016-5131 and some other bugs, but not what Suse
calls CVE-2016-9597: https://bugzilla.suse.com/show_bug.cgi?id=1017497
The bugzilla discussion seems to indicate that the CVE is referenced
incorrectly and only shows reproducing when using command-line flags
that are considered "unsafe".
CVE-2016-9318 also remains unfixed, as I consider their reasoning OK:
https://lwn.net/Alerts/714411/
/cc #22826.
This is because libxml/libxslt are not the only implementations that
respect $XML_CATALOG_FILES.
Also, look in share/xml for catalogs (in addition to the
now-deprecated xml/dtd and xml/xsl).
