HTML::Bare versions through 0.04 for Perl will hang in an infinite loop when parsing malformed attributes.

The parsercparse function never advances the attribute-parse state cursor on certain malformed attribute forms, looping forever.

Nameless attributes such as "<a ='c'>" or unbalanced quotes "<a b='''''''c'>" can trigger this condition.

Note that the latest version available on CPAN is version 0.02. Newer versions are available on the git repository.

HTML::Bare versions through 0.04 for Perl have an unbounded character lookahead.

The parsercparse function attempts to check for multicharacter strings such as "<![CDATA" or element terminators such as ">" without checking that the offsets are within the buffer.

Truncated strings such as "<a/" can trigger an out-of-bounds read.

Note that the latest version available on CPAN is version 0.02. Newer versions are available on the git repository.
