The remote Debian host is missing a security-related update.
David Golden of MongoDB discovered that File::Spec::canonpath() in Perl returned untainted strings even if passed tainted input. This defect undermines taint propagation, which is sometimes used to ensure that unvalidated user input does not reach sensitive code. The oldstable distribution (wheezy) is not affected by this problem.
Upgrade the perl packages. For the stable distribution (jessie), this problem has been fixed in version 5.20.2-3+deb8u2.
