  "title": "libmime-tools-perl: MIME::Field::ParamVal versions before 5.521 for Perl allow CPU exhaustion via unclosed comments in header parameters",
  "description": "MIME::Field::ParamVal versions before 5.521 for Perl allow CPU exhaustion via unclosed comments in header parameters.  The comment pattern used to parse Content-Type and Content-Disposition parameters scans from each \u0022(\u0022 to the next \u0022)\u0022. In a field with no \u0022)\u0022, every \u0022(\u0022 scans to the end of the header and fails, so parsing takes time quadratic in the header length. The field is parsed again on each attribute lookup, several times per MIME entity.  A 40 KB header takes about 7 seconds to parse once.",
