Subject: ensure File::Spec::canonpath() preserves taint
|
|
|
|
Previously the unix specific XS implementation of canonpath() would
|
|
return an untainted path when supplied a tainted path.
|
|
|
|
For the empty string case, newSVpvs() already sets taint as needed on
|
|
its result.
|
|
|
|
This issue was assigned CVE-2015-8607.
