Package: perl-modules
Version: 5.18.1-3
Severity: important
Control: affects -1 msva-perl
in perl 5.14.2-21, the following command returns cleanly:
perl -wTMModule::Load::Conditional -e
'Module::Load::Conditional::can_load(modules => { 'Test' => undef });'
0 dkg@wheezy:~$ perl -wTMModule::Load::Conditional -e
'Module::Load::Conditional::can_load(modules => { 'Test' => undef });'
0 dkg@wheezy:~$
but in perl 5.18.1-3, it fails harshly:
0 dkg@alice:~$ perl -wTMModule::Load::Conditional -e
'Module::Load::Conditional::can_load(modules => { 'Test' => undef });'
Insecure dependency in eval while running with -T switch at
/usr/share/perl/5.18/Module/Metadata.pm line 631, <GEN0> line 23.
25 dkg@alice:~$
This appears to mean that any code running in taint mode that uses
Module::Load::Conditional::can_load will fail hard. This is causing a
crash in msva-perl, which deliberately runs in taint mode and also may
conditionally load a handful of pre-known modules if they are present
on the system.
Marking this as important since it breaks msva-perl and probably other
code.
