Estado: AnalizadaAlta (7.5)—

Text::Minify::XS versions from 0.3.0 before 0.7.8 for Perl have a heap overflow when processing some malformed UTF-8 characters.

The minify functions mishandled some malformed UTF-8 characters, leading to heap corruption.

Note that the minify_utf8 function is an alias for minify.
