Hi,

This patch fixes CVEs of libxml2. The changes to 'runtest.c' in
'libxml2-CVE-2017-9049+CVE-2017-9050.patch are removed since they
introduce test failure. The changes only enable new tests so it should
be fine to remove them.
Attachment: 0001-gnu-libxml2-Fix-CVE-2017-0663-7375-7376-9047-9048-90.patch
Cheers,
Alex

Thanks for this! I think we have to graft this fix since changing
'libxml2' would rebuild 2/3 of the tree. Can you try that?

PS: Do you have a Savannah account? I'm sure Ludo or someone can add
you given the steady rate of quality commits.

Sure, here is the new patch:
Attachment: 0001-gnu-libxml2-Fix-CVE-2017-0663-7375-7376-9047-9048-90.patch
Previously, I had a Savannah account, but then I deleted it, since I
didn't use it. Now I realize I cannot create a new account with the same
username... I am asking for help from the Savannah admin.

Pushed, thanks! I added tabs before the line breaks in gnu/local.mk,
but otherwise untouched.

Side note: I think we should start adding patches as origins instead of
copying them wholesale, to try and keep the git repository slim.
