  • Apache2 with mod_perl2
  • TWiki TWikiRelease04x00 rev #9795
  • Language: de (I18N enabled)
  • Perl taint mode enabled globally
  • Locale::Maketext v1.10


Accessing TWiki (view, edit, attach, ...) caused a Insecure dependency in eval while running setgid at /usr/lib/perl5/5.8.7/Locale/Maketext/Guts.pm line 247. error message; not regularily, but too often.

Apache's errorlog shows:

This is caused by a known bug in Locale::Maketext. Also see http://rt.cpan.org/Public/Bug/Display.html?id=5521


Perl Taint mode was switched on globally. I18N was activated. Maketext seems not to be taint-safe. frown
