Comment 2 Daniel Veillard 2015-11-03 04:51:04 UTC

I don't think Fedora 22 is affected as 2.9.2 which ship it it has xz
support disabled due to a bug in that release

thinkpad2:~/XML -> /usr/bin/xmllint test.xz
test.xz:1: parser error : Start tag expected, '<' not found


^
thinkpad2:~/XML -> rpm -qif /usr/bin/xmllint
Name        : libxml2
Version     : 2.9.2
Release     : 4.fc22

I would assume versions in mingw and EPEL are also 2.9.2 so 1277149 and 1277150
can be closed in a similar way
