Bug#561970: libdate-manip-perl: cannot be used in taint (-T) mode

[Scott Barker]

Package: libdate-manip-perl
Version: 6.05-1
Severity: normal

Perl scripts cannot be run in taint mode when using Date::Manip. This simple
perl script:

#!/usr/bin/perl -T
use Date::Manip;

fails with the following message:

Insecure $ENV{PATH} while running with -T switch at /usr/share/perl5/Date/Manip/TZ.pm line 588.
Compilation failed in require at ./test line 3.
BEGIN failed--compilation aborted at ./test line 3.

This seems to be a result of the TZ methods including commands to be run
with the _cmd subroutine.

Following up, it appears that the problem is that Date::Manip::TZ does
not understand SystemV timezones as used by Debian. My /etc/timezone
file contains:

SystemV/MST7MDT

Changing it to:

America/Edmonton

fixes the insecure path taint error.
