NVD description

XML::Bare versions through 0.53 for Perl have an unbounded character lookahead. The parserc_parse 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.
