Description

HTML::Bare versions through 0.04 for Perl will hang in an infinite loop when parsing malformed attributes. The parserc_parse function never advances the attribute-parse state cursor on certain malformed attribute forms, looping forever. Nameless attributes such as "" or unbalanced quotes "" can trigger this condition. Note that the latest version available on CPAN is version 0.02. Newer versions are available on the git repository.
