The _compile function in Maketext.pm in the Locale::Maketext
implementation in Perl before 5.17.7 does not properly handle
backslashes and fully qualified method names during compilation of
bracket notation, which allows context-dependent attackers to execute
arbitrary commands via crafted input to an application that accepts
translation strings from users, as demonstrated by the TWiki
application before 5.1.3, and the Foswiki application 1.0.x through
1.0.10 and 1.1.x through 1.1.6.
