4Subject: [PATCH] perl: fix CVE-2015-8607
5
6ensure File::Spec::canonpath() preserves taint
7
8Previously the unix specific XS implementation of canonpath() would
9return an untainted path when supplied a tainted path.
10
11For the empty string case, newSVpvs() already sets taint as needed on
12its result.
13
14This issue was assigned CVE-2015-8607. [perl #126862]
